In 2013 Osram Opto Semiconductors introduced blue laser diodes that have an efficiency of 30% onto the market. At a wavelength of 450 nm, versions with an optical output power of up to 50 W are currently available. The PLPM4 450 model holds 18-20 multi-mode laser chips in a butterfly housing. They are used for illumination tasks and in laser projection. Laser diodes were developed in the cyan-colored wavelength of 488 nm for biomedical, medical, and measurement technology. They have an output power of 60 mW and are suited for both pulsed and cw operation.
