The HL63520HD from Ushio Opto Semiconductors is a 638 nm AlGaInP Laser Diode. This laser diode provides a pulse optical output power of 3.5W (Pulse period=120 Hz, duty=30%) in the operating temperature range from -10°C to 45°C. It also achieves a pulse optical output power of 2.5W at an operating temperature upper limit of 55°C. The red laser diode achieves an optical output power of 2.4W even in CW operation and realized the MTTF of over 20,000 hours. It can be incorporated into projectors in both pulse and CW operation modes. It is available in a 9 mm TO-can package and is ideal for laser projector and optical equipment applications.
