Melles Griot DPSS lasers are compact and reliable, with minimal heat generation and high resistance to mechanical shock and vibration. A compact laser head delivers excellent output power and pointing stability, thanks to state-of-the art thermal management and current control, which improves performance and reliability in harsh environments. A choice of fiber optic and free space beam delivery is available for most products.

We offer yellow, green, and blue DPSS laser systems in a wide range of wavelength and power options.  

All our laser products can be customized to meet your exact application requirements.

  • All solid-state for reliability
  • Stable output from 10°C to 40°C
  • RS-232 interface
  • CDRH and CE compliant

Frequency-multiplied diode-pumped solid-state (DPSS) lasers are an exciting tool for OEM applications. They combine the beam quality of a gas laser and the small sized and efficiency of a diode laser to provide visible output in the blue, green, and yellow wavelength regions. Because of their size, efficiency, power, and single wavelength, these lasers are ideal for use in microscopy, Raman spectroscopy, particle measurement, and graphics applications.

Melles Griot doubled DPSS lasers are convection or forced-air cooled and come in a variety of package configurations. Output powers range from a few milliwatts to as high as three watts. In many applications, the green lasers can be used to replace green helium neon lasers (543 nm) or air-cooled argon lasers operating at 514 nm, and the blue lasers can be used to replace argon lasers operating at 488 nm. Our new yellow DPSS lasers, operating at 561 nm, are ideally suited for fluorophre excitation, particulary for Rhodamine, ROX, and Alexa Fluor dyes, and are a highly reliable, drop-in replacements for argon/krypton lasers operating at 568 nm. Blue and yellow DPSS lasers operate in a single longitudinal mode, providing a coherence length in excess of five meters.
