The BWB laser series is a line of solid-state diode lasers and diode pumped solid-state lasers. Compact and self-contained, the BWB series emits a pure TEM00 beam with diffraction limited performance and a typical M2 of 1.4. Available in UV (405 nm) and blue (440 nm, 475 nm) with variable power options, these modules are ideal for demanding applications such as metrology, photoluminescence, printing, illumination, scanning, inspection, particle counting, and a variety of biomedical applications. These OEM laser modules maintain outstanding optical performance over a broad temperature range, guaranteeing minimal power fluctuations and virtually eliminating high frequency noise. They have the world’s smallest OEM controller with power consumption < 5 Watts. They have been qualified for use in some of the most demanding high-end instruments, with deployments in the tens of thousands. The 375 nm, 405 nm, and 440 nm systems replace bulky, expensive gas ion lasers for biomedical and fluorescence applications without sacrificing beam quality.

Low Noise
The BWB can be operated in a wide temperature range (10˚C - 35˚C) with a stable, quiet laser output power at most wavelengths. The BWB has a proven history of RMS noise stability < 1.0%. The combination of excellent beam characteristics (such as mode quality, low divergence, and brightness) makes the BWB laser series suitable for beam focusing as well as long distance beam positioning.
