Red Laser Diode
Mitsubishi Electric Europe BV, Semiconductor European Business GroupRequest Info
Mitsubishi Electric Europe BV has introduced a 638-nm red laser
diode. The ML520G72 offers high output power and is suited to picoprojector applications
or other portable display systems requiring a red light source with high brightness.
Its 500-mW output power achieves a luminous flux of up to 60 lm as opposed to the
10 lm offered by LED-based projectors, according to the company. Conversion efficiency
from electrical to optical power is 32% at 500 mW and at a case temperature of 25
°C. This helps to reduce power consumption and therefore to extend the battery
lifetime. Over the temperature range of –5 to 40 °C, the laser diode can produce
up to 500 mW of continuous-wave power, and it can provide pulsed laser light of
600 mW at 50 °C when operating with a maximum duty cycle of 25% at frequencies
of at least 50 Hz.
