Coherent Launches Turnkey Ultrafast Seed Laser

The new Vitara-S from Coherent Inc. (Santa Clara, CA) (Nasdaq: COHR) is a hands-free, integrated, ultrafast oscillator primarily designed to seed Titanium:Sapphire (Ti:S) amplifiers.  The new member of the Vitara family uses the same state-of-the-art technology as other Vitara products and delivers the same superior beam quality and power stability, operating with a fixed bandwidth of >70 nm centered at 800 nm.  The compact laser head incorporates one of Coherent’s unique Optically Pumped Semiconductor Lasers (OPSL) as pump laser.

Unlike other Vitara models that provide bandwidth and wavelength adjustability, the fixed operating point of Vitara-S makes this laser the simplest, most cost-effective and hands-free solution for amplifier seeding applications and for other ultrafast broadband applications requiring a fixed wavelength and power.

Vitara-S is the optimum choice for seeding kHz class Ti:S amplifiers, such as the Coherent Legend series, as well as high repetition amplifiers, such as the Coherent RegA series, or any other Ti:S ultrafast amplifier system. Its large bandwidth makes it equally suited to seed short pulse (~ 30 fs) amplifiers as well as 100 fs to ps-class amplifiers.

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 Nigel Gallaher, product manager, Research Scientific Lasers Business Unit, at
