KLASTECH-Karpushko Laser Technologies GmbH, launched its revolutionary new 266nm laser at Photonics West 2010.

The new DPSS laser provides continuous wave (CW) output at 266nm. Christened the VERVE this laser utilises the company’s next generation laser technology which provides for significant second harmonic conversion efficiency improvements over traditional architectures. The technology works by employing a dual cavity impedance matched design to ensure that fundamental wavelength generation is maximised at all times resulting in a quadratic increase in second harmonic generation. In fact to produce 266nm the same principles are utilised to ensure further enhancement of the fourth harmonic generation. A further cavity is employed thereby ensuring that impedance parameters are matched right through the frequency conversion chain.

The result is the world’s smallest 100mW laser with massively reduced power consumption and minimal heat generation. The VERVE requires no water cooling and now that the thermal management issues common with other formats are negated, the laser remains mechanically stable throughout operation ensuring the beam pointing stability is maintained to better than 10µrad/°C. Thanks to the miniaturised cavity the UV optics can be vacuum sealed for life in a nitrogen atmosphere so there is no need to provide a re-circulating nitrogen purge thus significantly reducing the cost of ownership and implementation.

In common with all other KLASTECH lasers the VERVE exhibits silent running (<0.5% rms noise), provides diffraction limited output beams with M2 better than 1.05, achieves long term power stability of <2% and as with all lasers based on the company’s new proprietary laser technology, produces inherently Pitch Perfect single frequency performance with a line width less than 1MHz.

Currently the company is taking advance orders for 25, 50 and 100mW versions with higher powers planned for 2010.

Applications include semiconductor inspection and UV spectroscopy.
