LASER 2009: new product focus
Products and announcements from Wavelength Electronics, NKT Photonics, Femtolasers Produktions and JENOPTIK Polymer Systems.
Temperature controller
The new PTC-CH Series temperature controller offers high-precision control and stability in a compact, chassis-mount package, claims Wavelength Electronics (Bozeman, MT). Designed to operate with the PLD-CH Series laser-diode drivers, the PTC-CH supports thermoelectric and resistive-heater operation with all sensor types. It provides user-configurable temperature setpoint and a TTL-compatible remote disable. With current up to 20 A, better than 1 mV accuracy and temperature stability across ambient of better than 1.4 mK, the PTC-CH Series is said to be ideal for applications such as electro-optical systems, benchtop inspection instruments and medical diagnostic equipment.

Benchtop fibre lasers
NKT Photonics, the result of a merger between Danish vendors Koheras and Crystal Fibre, is to introduce a new version of its AdjustiK and BoostiK series of fully integrated DFB fibre-laser benchtop systems. The optical design is based upon the third-generation KOHERAS BasiK laser engine, featuring a digital control interface and power upgrade feature. Target markets are any R&D and scientific applications that require high frequency stability and low-noise operation. The fibre lasers are offered at custom specified wavelengths within the C- and L-bands as well as within the 1.03-1.12 micron wavelength range. The AdjustiK series provides up to 200 mW of optical output power; the BoostiK series up to 1 W.

Ultrabroadband light source
The new INTEGRAL OCT light source supports ultrahigh-resolution optical coherence tomography (OCT), providing an ultrabroad bandwidth to reach sub-2 microns in axial resolution as well as ample power for ultrahigh-speed scanning. That’s the claim of Femtolasers Produktions, Austria. Applications include 3D imaging, spectroscopic and polarization-sensitive OCT, imaging of individual cells and subcellular structures, as well as non-destructive quality control. Specifications include: output power (ex fibre) >40 mW; centre wavelength of 800 nm; and bandwidth at 3 dB >150 nm.

Micro-optics for micro projection
JENOPTIK Polymer Systems, Germany, and MEMS Optical (also part of the JENOPTIK group) will be presenting a double-sided microlens in plastic that’s compatible with series production. A double-sided microlens array enables homogenization of laser sources as well as beam guidance in laser projection systems. The new product is a response to increasing demand for micro projectors in consumer applications such as laptop computers and mobile phones. “Injection-moulding technology allows for joining design mounting and alignment features as an integral part of the optical component to aid in packaging and system assembly,” says JENOPTIK.
