Single Frequency CW DPSS 266 nm Laser BRaMMS-Quartetto-266

Single Frequency CW UV Quartetto-266 diode pumped solid state lasers provide users unrivaled beam quality and reliability with optical output powers of 10-200 mW. Based on a highly reliable frequency doubled laser diode the Quartetto-266 lasers have genuine single frequency and wavelength stability. The lasers emit an optical beam in single-spatial-mode (M² <1.2), and allow a minimum focusing and uniform illumination of the sample.

The patented BRaMMS technology provides new wavelengths previously unattainable by CW single frequency DPSS lasers in UV, visible and near IR. It utilizes the spectrum discriminatory feature of a Michelson interferometer setup within a spectral range preselected by Volume Bragg Grating. This suppresses all but one lasing longitudinal mode within a laser cavity, hence – Bragg Range Michelson Mode Selector (BRaMMS).
Due to significantly lower power consumption for any required output and the resulting simplified thermal management, the BRaMMS laser technology provides up to 10 times wider range of output power scalability from the smallest footprint.
