Multi-chip laser diode module delivers 50W optical output

OSRAM OPTO PLPM4 450 compact laser multi-chip package can pack up to 20 blue laser chips into a single ‘butterfly’ package for projection applications. Device doubles the optical output of the individual chips, providing an overall blue light output of 50W. Blue laser diodes in combination with a converter wheel, which converts part of the blue light into the two primary colors of red and green, are used as the light source for laser projectors. Product dimensions are 25.5mm x 35mm (emission surface 16mm x 16.5mm), with optical output power of 50W (at a package temperature of 50C). Product’s wavelength is 440nm to 460nm, plus a lifetime (50% reduction in light), up to 20,000-hours (depending on ambient conditions).
