Single Frequency CW DPSS 515 nm Laser BRaMMS-Duetto-515

Single Frequency CW DPSS 515 nm Duetto-515 diode pumped solid state lasers have been developed to meet the highest requirements in OEM applications. The characteristics of the laser output beam is optimized for high performance, excellent mode quality, excellent long-term stability, excellent directional stability and a long service life. With a linewidth <0.5MHz the laser is ideal for applications that require high coherence length and spectral stability.

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.
