High-power laser diode


The new high power laser diode PL TB450 from Osram Opto Semiconductors is mounted in a compact TO-56 package and features an optical power of 1.4 W, making it particularly suitable for high-quality professional projectors such as those used in offices, conference rooms, and home cinemas. The latest in Osram's portfolio of lasers on indium-gallium-nitride substrates, the PL TB450 is also excellent for a range of other applications from laser systems for stage and decoration illumination to medical applications.

Professional projectors with a luminous flux of more than 1000 lm are the main area of application for the new PL TB450. With a wavelength of 450 nm, it produces the exact blue laser light desired and, with 1.4 W (at room temperature and a current of 1.2 A), the high optical power required.

Thanks to its excellent efficiency of 27 percent (the ratio of light produced to electric power consumed), the temperature of the laser will rise only slightly when in use, giving it a long service life of up to 10,000 hours at 40° C in continuous operation, depending on its use. The long lifetime of these laser diodes ensures maintenance-free operation of projectors at low energy consumption.
