PRODUCT UPDATE PRODUCT UPDATE LASERS PUFL UV fibre lasers WTR series laser module
Snake Creek Lasers has introduced the WTR series, an industrial-grade OEM laser module. The WTR module is proven for operation from -29°C to +43°C ambient temperatures, and to withstand severe shock and vibration conditions. With 10 to 50VDC input
voltage requirement, the laser is easy to integrate into OEM applications. It offers two auxiliary 12VDC outputs and the laser can be triggered with alternative latch or momentary trigger modes. The WTR is currently available with output powers up to 50mW at 532nm or 30mW at 635nm wavelengths. Depending on beam forming optics, the laser can be tested to CDRH Class 2, 3A, or 3B requirements.

AMS Technologies has introduced a new series of UV
fibre lasers. The PUFL series UV fibre lasers are pulsed laser sources emitting at 355nm and delivering a high peak power pulse in a very compact package. The 355nm series is a UV laser based on the combination of a powerful 1.0μm fibre laser and a compact and efficient frequency converter. The
TG400 green laser
Technifor has expanded its laser offering with the TG400
green laser. With the laser’s 532nm wavelength, this system can be used for marking materials that do not interact with other classic laser equipment, such as YAG, YVO4 fibre, or CO2
, . This solution is designed with
output beam is near Gaussian and collimated.
The laser system is delivered with an interface module that keeps the frequency converter at constant temperature. The source is ideal for wafer inspection, Raman spectroscopy, aerosol detection and biological
experimentation applications, such as fluorescence excitation imaging.

medical, electronics, electrical, and plastics marking applications in mind. It will enable the marking of sensitive materials such as silicon, reflective metals, printed circuits, ceramics, and a range of plastics. The 30µm beam delivers high marking quality, which allows the laser to mark small characters and Data Matrix codes. The
TG400 enables surface marking with reduced heat-affected zone, avoiding material damage or distortion.
The TG400 green laser software, developed by Gravotech Group, helps the implementation of identification and traceability solutions.

TEST AND MEASUREMENT PowerMax-Pro sensors
Coherent has released a new type of laser power sensing detector that combines the broad wavelength sensitivity, dynamic range and laser damage resistance of a thermopile with the response speed of a semiconductor photodiode. The detector relies on a novel, thin-film technology to create a device which rapidly senses thermal changes due to incident laser energy. Unlike traditional thermopile detectors, in these PowerMax-Pro sensors, heat flows vertically through a film which is only microns thick, rather than radially to the edge of the device over a distance of several centimetres. The result is a
42 M2-200s beam analyser of the M2
measurement response time less than 10µs, as compared to more than one second for traditional thermopiles. Plus, these detectors can operate over a spectral range as broad as 300nm to 11µm, and incorporate a large 30 x 30mm active area. The high response speed of PowerMax Pro sensors is particularly advantageous in commercial applications.

LASER SYSTEMS EUROPE ISSUE 23 • SUMMER 2014
Ophir Photonics has launched the newest version -200s, the company’s
camera-based beam propagation analyser. The M2
-200s is an ISO
11146-compliant system that automatically measures laser beam quality in less than two minutes and features a robust design that supports continuous operation. The latest version enhances the system’s robust packaging with a new motor controller that decreases noise from motor movement by 30 per cent. The M2
-200s is a compact,
portable unit that features a CCD camera for use with pulsed or CW lasers, 266-1,300nm. The system automatically measures M2
, beam waist location and width, divergence, astigmatism, asymmetry ratio, and the Rayleigh range for each axis. Input beam sizes can range from 0.5-10mm. Manual mode is available for beams that are too large, too small, or for wavelengths outside the standard optical train. The M2
-200s supports both
the 64-bit and 32-bit versions of Windows 7.
