Development of New Red Laser Diode for Projectors offering Industry’s Leading Output
Mitsubishi Electric has developed a 638-nanometer (nm) wavelength red laser diode (LD) with output power of 1.8 W at continuous-wave operation, clicking the world’s highest level among the 638-nm LDs used as a light source for projectors. The luminosity of the new diode exceeds 220 lumens due to lasing at short wavelength.
Furthermore, it has industry leading electrical conversion efficiency of 38% at 1.8 W at 25 degrees Celsius resulting in reduction of power consumption. It offers excellent heat dissipation due to use of large TO-can package with diameter of 9.0 mm.
