Coherent has launched the Verdi G7, delivering what is said to be the highest power level yet for the company's Verdi G range of low-noise CW lasers.
The lasers are based on optically pumped semiconductor laser (OPSL) technology.
The Verdi G7 provides a minimum power of 7W in a TEM00 output beam.
Intended principally for pumping Ti:Sapphire laser systems, this new laser delivers high reliability, low cost of ownership and 0.03 per cent rms noise.
All Verdi G lasers come with a comprehensive two year/10,000hr warranty.
In OPSLs, the gain medium is a semiconductor chip that has a near-zero upper state lifetime.
This eliminates the green-noise component of laser output noise that is found in 532nm DPSS lasers operating on multiple longitudinal modes.
Verdi G lasers deliver low noise without single-mode 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.
The efficiency of the OPSL design means that the Verdi G lasers use only a single diode array.
The Verdi G7 is suitable for pumping ultrafast and CW Ti:Sapphire laser systems for applications in spectroscopy, pump-probe dynamics and materials research.
OPSL technology is field proven in these applications as the integrated pump laser in Coherent's Mantis - a one-box femtosecond oscillator.
