Coherent has released a 10W, very low noise, CW green (532nm) laser intended for cost-effective pumping of Titanium:Sapphire oscillators and amplifiers.
The Verdi G10 is the highest-power model in the Verdi G range, which utilises Coherent's next-generation, optically pumped semiconductor laser (OPSL) technology to deliver reliability, compact size and low cost of ownership.
Because Verdi G series lasers are based on OPSL technology, they do not suffer from either the 'green noise' or thermal lensing issues that limit the performance of competitive multi-mode lasers based on diode-pumped solid-state (DPSS) technology.
As a result, they exhibit extremely low noise (less than 0.02 per cent rms) across a wide frequency spectrum (10Hz to 100MHz).
The lack of thermal lensing means the output power of the Verdi G10 can be smoothly adjusted from 10 to 100 per cent of the maximum value with no effect on beam quality or beam pointing stability (which is less than 2urad/C).
The Verdi G10 laser is suitable for pumping ultra-fast and CW Titanium:Sapphire laser systems for all applications in spectroscopy, pump-probe dynamics and materials research.
This includes CEP-stabilised systems where achieving low phase noise is critically dependent on using a low-noise pump laser.
In addition, the Verdi G10 is the first non-DPSS laser to provide sufficient power for pumping high-repetition-rate ultrafast amplifiers such as the Coherent RegA series.
