Coherent Launches 10 Watt Low-Noise Green Laser

Coherent Inc. (Santa Clara, CA) (Nasdaq: COHR) has released a new 10 Watt, very low noise, CW green (532 nm) 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 utilizes Coherent’s next-generation, 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% rms) across a very wide frequency spectrum (10 Hz to 100 MHz).  And, the lack of thermal lensing means the output power of the Verdi G10 can be smoothly adjusted from 10% to 100% 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-stabilized 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.

Founded in 1966, Coherent, Inc. is a Russell 2000 Index company and a world leader in providing laser-based solutions to the commercial and scientific research markets.  Please direct any questions to Brandon Morioka, product line manager, at (408) 764-4373.  For more information about Coherent, including product and financial updates, visit our website at
