Coherent Expands Low-Noise Green Pump Laser Product Line
In OPSLs, the gain medium is a semiconductor chip which has a nearzero upper state lifetime. This eliminates the "green noise" component of laser output noise that is found in 532 nm DPSS lasers operating on multiple longitudinal modes. So Verdi G lasers deliver exceptionally low noise yet without singlemode operation. And because the gain medium is a thin chip that is cooled from its rear surface, it does not suffer from thermal lensing effects. As a result, the output power of Verdi G lasers can be smoothly adjusted with no effects on beam quality, divergence or beam pointing. Plus the efficiency of the OPSL design means these Verdi G lasers use only a single diode array, significantly lowering the longterm cost of ownership.
The Verdi G7 is ideal for pumping ultrafast and CW Ti:Sapphire laser systems for applications in spectroscopy, pumpprobe dynamics and materials research. OPSL technology is already fieldproven in these applications as the integrated pump laser in Coherent's stateoftheart Mantis(TM) - a onebox femtosecond oscillator.
