Mitsubishi launches a 638-nanometer (nm) wavelength red laser diode (LD), the ML501P73, with an output power of 1W, the world’s highest among 638 nm band LDs. The ML501P73 diode is ideal for pico projectors and other portable display systems that require a high-brightness red light source.
Highest recorded output power of 1 W at 638 nm for micro projectors
- The product offers a pulsed output power of 1W, currently the world’s highest in 638 nm band
- Luminosity as a red light source exceeds 120 lumens (lm) due to lasing at short wavelength
- The product has an industry-leading electrical conversion ratio of 35% at 1W at a temperature of 25 degrees C, enabling the reduction in power consumption
Operational at temperatures between -5 degrees C and + 40 degrees C
- The product can emit 1W in pulsed output and 0.5W in continuous waves within an operating range of -5 degrees C to + 40 degrees C. In the pulse condition, the duty ratio is less than 33% and the frequency is higher than 50Hz.
