Mitsubishi announces highest power Red Laser Diode for Projectors
Mitsubishi Electric will launch a new continuous-wave (CW) laser diode (LD), the ML562G85, offering a world-record output power of 2.1W and a 639nm red light for projectors on February 1, 2017. The LD's red colour and low power consumption are expected to be adopted for large-venue laser-based projectors requiring high brightness.
It has been a technical challenge to produce red LDs offering high output at high temperature using a lasing wavelength not exceeding 640nm, the preferred maximum for achieving necessary luminosity.
Mitsubishi Electric succeeded in developing its new CW high-power red LD that operates at high temperature by using original high-power technology, including an optimized LD structure.
Product features include an optimised epitaxial structure and emitter size that enables world-record 2.1W output (CW), 4.2 times greater than that of the company's current model.
The large 9.0-mm-diameter transistor-outline can (TO-CAN) package improves heat dissipation, providing an operating temperature range of 0 to 45degC at 2.1W (CW), compared to the current model's range of 0 to 40 degC at 0.5W (CW)
