808nm, 4.2W Laser Diode

The JOLD-4.2-BAXH-1E laser module from Jenoptik is a high brightness diode laser module that is designed for a variety of applications, including illumination, instrumentation, and pumping of solid-state lasers. It has a high optical output power of up to 4.2 W cw and a center wavelength of 808 nm. The laser module has a low divergence of 8 mrad, with M2x ~ M2y < 20, and a homogeneous, symmetric beam profile. The beam is polarized (50:1) and the laser module is housed in a compact, hermetically sealed package.

The laser module is passively cooled and operates in CW mode, with power modulation only between threshold and maximum current. The laser module has a typical operation current of 6.5 A and a maximum operation current of 9 A. It has a typical threshold current of 1.4 A and a maximum threshold current of 2 A. It is designed to operate in a non-condensing atmosphere and has a storage temperature range of -20 to +70 °C. The expected lifetime of the laser module is greater than 10,000 h (constant current).
