Coherent has released a new 10W, low noise CW green (532nm) laser intended for cost-effective pumping of Titanium:Sapphire oscillators and amplifiers. The new Verdi G10 now becomes the highest power model in the Verdi G family, which utilises Coherent's optically pumped semiconductor laser (OPSL) technology to deliver a unique combination of high performance, exceptional 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 (<0.02 per cent rms) across a very wide frequency spectrum (10Hz to 100MHz). And, 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 <2 μrad/°C).
The Verdi G10 laser is ideal for pumping ultrafast 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.
