The Optoelectronics Company has announced that USHIO's new high-power laser diodes are now in mass production. As laser projection equipment and laser TVs get smaller and smaller, these two new diodes offer manufacturers the massive optical power output they need to enable better image quality, more vivid colour and greater clarity.

The HL63283HD is a visible wavelength laser diode in a 9mm-diameter CAN package with high heat dissipation and high wall plug efficiency of 40 per cent. It offers an impressive 1.2W optical output power at a typical centre lasing wavelength of 637nm at 25°C. Its operating temperature range is -10°C to +45°C, its typical operating voltage is 2.3V and its LD reverse voltage is 2V with a typical threshold current of 340mA and an operating current of 1,300mA. The typical beam divergence parallel to the junction is 10°, and 33° perpendicular to the junction.

The HL63290HD is also a visible wavelength laser diode in a 9mm-diameter CAN package with high heat dissipation and high wall plug efficiency of 40 per cent. However, it offers even more optical output power of 2.2W CW at a typical centre lasing wavelength of 638nm at 25°C. Its operating temperature range is -10 to +55°C, its typical operating voltage is 2.4V and its LD reverse voltage is 2V with a typical threshold current of 600mA and an operating current of 2.4A. The typical beam divergence parallel to the junction is 10°, and 33° perpendicular to the junction.
