Single-chip laser diode

24 November 2010 Opto-Electronics

Hamamatsu Photonics has introduced a brand new 5 W CW single-chip laser diode, the L11374. This new diode is a lateral multimode type, with a broad emitting area of 100 μm and a centre wavelength of 915 nm. It adds to Hamamatsu’s current range of 1 Watt to 8 Watt single-chip laser diodes available at wavelengths from 808 nm to 1064 nm.

The L11374 features very long lifetime characteristics, and is available in a head-out OHS package. It has potential applications in both the medical and industrial fields, for marking, engraving and surface treatments.

Hamamatsu also offers a range of laser bar devices, supplied either as bare diodes, or provided as a module, with CW powers up to 60 W per bar and a choice of water cooling, peltier cooling or Hamamatsu’s patented funryu cooling technology. Stacked bar arrays (with up to several kilowatts output power), fibre-optic coupling and a choice of other wavelength laser diodes are all available to specific customer request.
