Klastech-Karpushko Laser Technologies is about to introduce the Verve 266nm laser, which it will exhibit at Photonics West 2010.
The new DPSS laser provides continuous wave (CW) output at 266nm.
The Verve utilises Klastech-Karpushko's Imat laser technology, which provides significant second harmonic conversion efficiency improvements over traditional architectures.
However, to reach 266nm, two Imat cavities have been employed running in tandem, thereby ensuring that impedance parameters are matched right through the frequency-conversion chain.
The result is a tiny 100mW laser with reduced power consumption and minimal heat generation.
The Verve requires no water cooling and the thermal-management issues common with other formats have been negated, helping the laser to remain mechanically stable throughout operation and ensuring the beam-pointing stability is maintained to better than 10urad/degC.
The miniaturised cavity allows the UV optics to be vacuum sealed for life in a nitrogen atmosphere, removing the need for a re-circulating nitrogen purge, therefore reducing the cost of ownership and implementation.
In common with all other Klastech lasers, the Verve exhibits silent running (less than 0.5 per cent rms noise), provides diffraction-limited output beams with M2 better than 1.05, achieves long-term power stability of less than two per cent and produces pitch-perfect single-frequency performance with a line width of 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.
