Coherent Introduces New, High Power, Compact Yellow Laser
Santa Clara, CA — Two new Compass lasers from Coherent, Inc. (Santa Clara, CA) deliver more power from their compact packages than any Compass system previously available. Specifically, the Compass 561 is now offered with either 40 mW or 25 mW of output power (at 561 nm) from a laser head measuring only 100 x 40 x 32.5 mm (3.94 x 1.57 x 1.28 in.). This unique combination of power and size means these all-solid-state lasers are well-suited for OEM bioinstrumentation applications, including confocal microscopy and live cell imaging. In particular, the yellow wavelength enables solid-state access to fluorophores, such as rhodamine series and Alexa Fluor dyes, which traditionally were excited only using krypton ion lasers.
Compass 561 lasers also offer superior performance in terms of output characteristics. For example, they possess the lowest noise specification (<0.25% RMS at 10 Hz to 1 GHz) of any yellow laser, resulting in data with a superior signal-to-noise ratio. High transverse mode quality (M2<1.2), coupled with excellent beam-pointing stability (<6 µrad/°C), make it possible to achieve and maintain excellent throughput with microscope optics. Compass 561 lasers are also extremely rugged and reliable because they use the same PermAlign manufacturing technology that has proven itself in over 40,000 Compass units currently in the field.
Founded in 1966, Coherent, Inc. is a Standard & Poor's SmallCap 600 company and a world leader in providing laser-based solutions to the commercial and scientific research markets.
