Yellow DPSS Lasers suit microscopy applications.

Press Release Summary:




Operating at 561 nm, 85 YCA series diode-pumped solid-state (DPSS) lasers produce single-frequency output to 10 mW with less than 3% peak-to-peak noise. Beam is nearly circular, with less than 1.1:1 aspect ratio; is linearly polarized; and has M2 factor of less than 1.2. Compact, conduction-cooled laser head incorporates thermoelectric cooling and automatic power control. Lasers are suited for confocal laser scanning microscopy.

New Yellow DPSS Laser Offers Improved Dynamics for Microscopy



Carlsbad, CA - Melles Griot introduces a new series of diode-pumped solid-state (DPSS) lasers operating at 561 nm. The new 85 YCA series produces single-frequency output with less than 3% peak-to-peak noise. "For the first time, all solid-state reliability and performance are available in this critical region of the spectrum," said Michael Atchley, Senior Product Manager for DPSS products at the Melles Griot Laser Group.

According to Mr. Atchley, 85 YCA-series lasers are particularly suited for confocal laser scanning microscopy and for exciting Rhodamine, ROX, and Alexa Fluor dyes. "The wavelength matches the absorption spectra much better than that from green HeNe lasers, and the systems are more reliable, stable, efficient, and long-lived than krypton or krypton/argon lasers operating at 568 nm," he added.

85 YCA-series lasers are available with output powers of up to 10 mW. The beam is nearly circular (<1.1:1 aspect ratio) and linearly polarized, and it has an M2 factor of less than 1.2. The compact, conduction-cooled laser head incorporates thermoelectric cooling and automatic power control for stable, long-term operation with power drift of less than 5% over 24 hours.

Melles Griot is a leading global supplier of photonics products including optical components and systems, lasers, motion-control systems, laser measurement instrumentation, opto-mechanical hardware, and vibration isolated optical tables and workstations. The company has manufacturing and distribution activities in 41 countries, serving industries as diverse as semiconductor, biomedical, metrology, and telecommunications. Melles Griot is a Barloworld Scientific company.
