Photonics Industries offers two very distinct versions of a tunable wavelength laser, the OPO series and the TU series. The OPO series is the first commercially available Optical Parametric Oscillator to produce pulse rates at a high repetition rate of up to 50 kHz. It is available in two models with a wavelength ranging from 1.5 um to 3.4 um. The TU series uses a Ti:Sapphire crystal in order to produce a wavelength ranging from 193 nm to 960 nm depending on the specifications and model.

Research Electro-Optics, Inc. (REO) has been a
leader in the fi eld of high performance and high
reliability Helium-Neon lasers for over twenty years.
The vast majority of our laser tubes manufactured
over the years have been incorporated into medical,
scientifi c and critical manufacturing instruments. This
experience, combined with our on-staff technical
expertise and fl exible manufacturing structure, makes
REO uniquely suited to supplying Helium-Neon lasers
for performance critical applications.
REO's primary strength in the Helium-Neon laser
market is our in-house optical fabrication and coating
capability. It is widely acknowledged that mirror
performance is one of the most critical factors in
maintaining consistently long laser life. Manufacturing
these components in-house is the best way to
develop insight into the technical factors affecting
mirror performance and to ensure consistent mirror
quality. Our technical insight into optimizing mirror
performance provides our laser products with
competitive advantages in terms of output power
and laser lifetimes. Utilizing enhanced designs and

The Photon etc. Tunable Source was originally developed for the wavelength calibration of astronomical instruments for the visible and the NIR spectral range. Narrow bandwidth, a large tuning range, and a highly precise and accurate wavelength were successfully achieved with this instrument.
Because of this successful development, Photon etc. is now offering Tunable Sources with different spectral resolutions for wavelength calibration of photometric and radiometric instruments in the visible and the NIR spectral range.
Due to the built-in flexibility of the Tunable Source, the type of source, or the spectral resolution, and thus the optical performance, can be modified to meet our customers' needs. Moreover, the Tunable Source is easily converted into a compact high-performance Monochromator.
The Photon etc. Tunable Source is an ideal instrument for wavelength calibration of both laboratory and field equipment, for which portable, durable, and resistant instruments are required.

Koheras AdjustiK™ and Koheras BoostiK™ Systems are narrow linewidth fiber laser turn-key benchtop systems based on a truly single mode, single frequency DFB (Distributed-Feedback) Fiber Laser with extremely high frequency stability and low phase and intensity noise.
The Koheras AdjustiK™ System is a single stage amplified system with up to 200 mW of output power, whereas the Koheras BoostiK™ System is based on dual stage amplification with up to 2 W of output power.
This range of benchtop laser systems is typically offered as rapidly deployable sources for research laboratories that wish to use it as a tool for scientific work and not spend time on setting up a laser system. The benchtop models are based on the Koheras BasiK™ Module seed technology and are upgradable in terms of output power. The systems are supplied with Koheras GraphiK™ software for the control and read-out of numerous laser parameters on a pc such as wavelength, output power, and RIN suppression.
A part from interferometric sensing and LIDAR, these laser systems are very useful sources for various scientific applications (more information available in the application section)

Simtronics is pleased to announce the put on the market of the GD1, a new generation of open path detector.
The GD1 innovates by creating a new standard of toxic gas detection. At the heart of the detector is a tuneable laser diode that eliminates environmental effects from sun, rain, and fog. The laser scans single absorption lines where there is no interference from other gases. This new technology constitutes an important progress with exceptional performances and a extreme reduced maintenance.
Unlike traditional methods for detecting H2S (MOS or EC cell), the GD1 needs no recalibration and can replace multiple standard detectors to cover the same risk. Compared to traditional detectors the GD1 offers:
• Faster detection
• Reduced maintenance
• A life calibration
• Fast acting
The GD1 is also available with a dual output gas configuration, Methane and Hydrogen Sulphide.
Supplied with worldwide hazardous area approvals. Suitable for use in SIL 2 systems.
With its level of detection lower than 5ppm and it is faster response time (T90 < 5 sec) the GD1 is ideal to ensure the personnel safety on petrochemical installations onshore or offshore or for the sites of treatment of waster water.
Furthermore, the GD1 offers real cost savings, using a single transmitter / receiver pair, the detector covers distances of up to 100 metres. Installation and maintenance costs are reduced as fewer devices are needed to cover the same risk as several point detectors.
As with all Simtronics’ products, the GD1 is designed for early detection of hazardous events. It’s built to work safely in extreme areas and withstand the hardest environments onshore and offshore.
