We are pleased to announce the arrival of the Opotek IR Opolette 100 Optical Parametric Oscillator (OPO) pumped by the Quantel Centurion 100Hz diode pumped Nd:YAG laser which would be particularly suitable for IR MALDI applications at 2.94µm.

The new IR Opolette 100 employs KTP crystals for the wavelength range 2.6-3.2µm and offers a pulse energy of >0.8mJ across this range at 100Hz (~1.1mJ at 2.94µm); see tuning curve. By comparison Opotek also has another ultra compact standard system using KTP crystals pumped by Quantel USA’s Ultra 20Hz laser which offers >1.5mJ at 2.94µm; see tuning curve.

IR Opolette tuning curve

Since MALDI-TOF applications also require samples to be illuminated in the UV, it is possible to add a UV option which will enable the user to access the 355nm output (>5.5mJ) from Opotek’s third harmonic module pumped with the residual 1064nm having pumped the OPO. The IR and UV are generated simultaneously though accessed separately; whilst operating in the IR the Second Harmonic Generator should be dephased in order to minimize residual background (phase matching adjustments available). It is simple to interchange between IR and UV beams.

All Opotek’s products are fully automated, reliable, flexible as well as easy to use and maintain. They are based on patented OPO designs and supplied with a control program that enables tuning from a computer via USB. The compactness of the Opolette system has been further improved now that the ULTRA pump utilises Quantel’s new ICE 450 compact, portable, easy-to-use power supply with detachable cables (at laser head and electronics) which can be used vertically or horizontally.

We are pleased to announce several technical advancements in the Lasos portfolio of Laser Diode Modules and Diode Pumped Solid State (DPSS) lasers used in confocal microscopy, flow cytometry and cell sorting applications.

The model VLK 0520 F (20mW at 408nm) and RLK 6040 F(40mW at 660nm) are new members of the LasNova-series 10/20 laser diode modules with integrated fibre coupling into Single Mode Polarization Maintaining (SM PM) fibre, and built into the same size package as our compact DPSS lasers. The pigtailed fibre coupling has a robust design, ensures long term stability of the laser output parameters and will give you the flexibility of being able to position the laser head remotely to your experiment.

Lasos can offer various options for the output connector, e.g. FC/PC or FC Ferrule and a collimated output beam for the red module. The laser can be modulated with an analogue input of up to 20MHz and with a digital input up to 100 MHz. We can also offer other models at 445nm, 473nm, 635nm and 680nm. Free-space versions of Lasos’ laser diode modules will be released later this year. 

The YLK 6150 T yellow DPSS laser with 50mW at 561nm is a new member of the LasNova 60 series and a significant improvement on the 20mW previously offered. The laser exhibits excellent beam quality (M2 ~ 1.2), output power stability (+/- 2% over 8 hours) and <0.5% rms noise (30Hz…100MHz) making this laser the best choice for fluorescence-driven imaging devices.

Lasos are offering this significantly higher power laser to compensate for fibre-coupling losses or optical throughput inefficiencies in the field of laser scanning microscopy and imaging devices.

Lasos have a long history in supplying gas lasers for many applications such as Printing, Medical, Biotechnology, Metrology, Holography and Barcode scanning. For example, Lasos manufacture extremely high specification and stable HeNe lasers with laser lifetimes of >20,000 hours, very good beam quality (M2 typically 1.1), <0.5% rms noise (30Hz…..10MHz), power stability (< +/- 5% , 8 hours after warm-up) and minimal angular drift as a function of temperature (0.05 mrad/ °C). Lasos’ universal fibre-coupling solution can be used with all their gas and solid state lasers, has high coupling efficiency (>70%) will not need to be realigned in the field.

Available in the UK from Lambda Photometrics Ltd; Stanford Research QMS series atmospheric sampling systems offer an efficient, cost-effective solution for a wide range of gas sampling applications such as on-line process monitoring, gas analysis, leak detection, troubleshooting and much more.  

Key features:

• 100, 200 or 300 amu systems
• Pressures from 10 mbar to 1 bar
• Better than 1 amu resolution
• <0.5 second response time
• Compact, transportable design 6 decades of dynamic range
• RGA Windows software
• RS-232 computer interface
   

The QMS gas analyzer (mass spectrometer) is capable of sampling gases at pressures from above atmospheric to as low as 10 mbar. It uses a two-stage pressure reducing inlet to sample gases at high pressure and is integrated with a residual gas analyser (RGA) detector. The state-of-the-art vacuum pumped bypass flow design enables a fast response time of less than 0.5 seconds, from the tip of the capillary to the RGA chamber.

The QMS can continuously sample gases at low flow rate of several millilitres per minute, and data is acquired continuously to allow on-line monitoring; as opposed to batch sampling which is conventionally employed by gas chromatographs. The mass spectrometer has excellent resolution of better than 1 amu with a detection limit of less than 1 ppm, and 6-decades of dynamic range for partial pressure measurements.

The QMS system is available in mass ranges of 100, 200 and 300 amu. It is packaged in a compact unit and can be easily transported. System operation is straightforward and does not require a detailed understanding of the quadrupole mass spectrometer, vacuum pumps or the pressure reducing inlet. All QMS systems are supplied with a Windows based control and analysis software package with a user-friendly graphical user interface. For more advanced users, the probe parameters can be easily integrated into user controlled programs through an ASCII command set. A stand-alone partial pressure monitor is available as optional extra.

Internal or external triggering at rates of up to 20Hz is standard, and an optional output sync. pulse can be specified for experiments or systems where sub-nanosecond accuracy is critical.

The NL100 has a user replaceable, sealed laser cartridge, warranted to maintain at least 70% of its energy for 20 million pulses or 2 years, though tests have proven that this figure is more likely to be ~80%. No mirror alignment is ever necessary in the NL100 as the laser optics are mounted on the plasma tube and factory aligned.

Stanford Research have a world-class reputation in scientific instrumentation, and none of their products have been obsoleted. This means we can provide you with a secure on-going supply of high quality nitrogen lasers, and is the reason why a growing number of OEM customers are switching to the Stanford Research NL100.

The system's new parallel data output format enables the user to obtain 1.24nm resolution with a 2-pass interferometer, while moving at velocities up to 500mm/sec. Four axes of displacement metrology can be measured using two ZMI 501 boards and the high power 7705 laser option (>350 mW).

High-speed data output features include quadrature, up/down pulses and parallel 32 bit. The platform accommodates 3U or 6U VME and stand alone interface options - in preference to more changeable PC based formats.

ZMI 501 is designed to provide cost effective stage metrology performance for OEMs. The system's higher velocity ensures increased throughput - with improved resolution resulting in better accuracy and repeatability. Compact design allows easier integration and a smaller footprint. Zygo's purpose-designed lasers have an expected lifetime of >50,000 hours - significantly reducing operating costs.

DMI solutions are already well established as the essential technology for improving stage position accuracy and control, since measurements are made at the plane of interest, effectively eliminating geometrical and parallax errors.

ZMI 4004 ZMI 4004 measurement board has been developed for highest performance applications such as lithography and calibration instrumentation, providing a 4-axis solution on a single 6U VME card - and requiring much reduced backplane space. Designed for use with Zygo's AOM based lasers, the board provides 0.15nm resolution and 2.55m/sec velocity with a 2-pass interferometer. Data age uncertainty is +/- 0.1nsec, providing unmatched dynamic accuracy and synchronization of all axes. DMI solutions are critical to ensuring accurate dynamic stage positioning during the lithography process, enabling significantly improved overlay and higher throughputs.
