405nm wavelength stabilised laser diodes

BFi Optilas, together with Photonic Products and Ondax, is launching a new range of 405nm wavelength stabilised laser diodes for applications such as Raman spectroscopy, flow cytometry and metrology/interferometry.

The 405nm blue-violet wavelength stabilisation is achieved by optical feedback using the Ondax Volume Holographic Grating (VHG) PowerLocker, which ensures a stable single longitudinal mode operation.

Features include wavelength stability (< 0.015nm/ºC), single longitudinal mode, compact size (standard 5.6mm TO package), wavelength locked to <±1nm, coherence length (~0.6m) and hermetic sealing. The power locked laser has a very low temperature dependence and precise centre wavelength over the locked region which enhances its performance.

The laser is suitable for use in data storage, embossed holograms, CD-mastering, diffraction grating fabrication, confocal microscopy, particle counting, fluorescence, non-destructive testing, microlithography and high speed printing. Other standard wavelengths are available at 403, 405, 407, 640, 658, 685, and 785nm. Custom wavelengths, packaging and accessories are available upon request.
