PLT5 Laser Diodes OSRAM Opto Semiconductors PLT5 Laser Diodes are single transverse mode semiconductor lasers with a high modulation bandwidth and are available in green and blue colours. The PLT5 laser diodes are available in a T056 package with photodiode and are an efficient radiation source for continuous-wave (CW) and pulsed operation. These laser diodes are available in different variants based on colour, optical output power and typical emission wavelength. Typical applications include laser projection, laser shows, biomedical applications and metrology.
