29 Oct 2009 Pro-Lite has added a 20mW version of its 488nm ChromaLase™ II diode laser module from Blue Sky Research. The laser employs a blue laser diode with integrated drive, control & protection electronics. The ChromaLase II 488 employs a blue laser diode conveniently packaged in a rugged module with integrated electronics for laser drive, power level control, diode protection and with direct modulation capability
The ChromaLase™ II 488 laser incorporates a blue semiconductor laser diode that has been equipped with a proprietary Blue Sky micro lens (μLens). The μLens shapes and corrects the inherent defects in the light from a normal semiconductor laser. The integrated beam correction results in a near-perfect Gaussian and circular beam shape and also helps correct the wavefront distortions inherent in laser diodes. This avoids the extra cost and complexity of external beam conditioning optics that are employed with normal diode lasers. |
