Single Frequency CW DPSS 442 nm Laser BRaMMS-Duetto-442

Single Frequency CW "blue" Duetto-442 diode pumped solid state lasers provide users unrivaled beam quality and reliability with optical output powers of 10-150 mW. Based on a highly reliable frequency doubled laser diode the Duetto-442 lasers have genuine single frequency and wavelength stability. The lasers emit an optical beam in single-spatial-mode (M ² <1.1), and allow a minimum focusing and uniform illumination of the sample.

Description

Details

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.
This technology allows any wavelength within the spectrum range from IR (around 2000 nm) through deep UV (<200 nm) operating in the CW Single Frequency regime.
All of this provides an unprecedented range of application, from holographic art to large scale structural analysis, from pharmaceutical instrumentation to cuttin gedge particle trapping techniques, from semiconductor wafer micro - processing to wind turbine power generation and avionic technologies and many many more.
