454nm, 30mW Narrow Line Width Laser Diode

454nm, 30mW Laser Diode Module Overview:

The Narrow Line Width Diode Laser from CNI Laser at 454 nm is a laser module that emits light at a wavelength of 454 nm with a spectral line width of less than 0.06 nm (or less than 0.03 nm with an extra heatsink). It operates in continuous wave (CW) mode and has an output power ranging from 1 to 30 mW, with power stability of less than 1%, 3%, or 5% over a four-hour period depending on the selected output power.

The laser has a near TEM00 transverse mode and M2 factor of less than 1.5, with a beam diameter at the aperture of approximately 2.5 mm and beam divergence of less than 1 mrad. The laser also has a polarization ratio greater than 50:1 (or greater than 100:1 as an optional feature) and can be operated at temperatures between 20°C to 30°C. It has a warm-up time of less than 15 minutes and an expected lifetime of up to 10,000 hours, with a one-year warranty provided by the manufacturer.
