WARABI, Japan, Dec. 20, 2017 — The Optoelectronics Co. has announced two new red laser diodes from Ushio Opto Semiconductors Inc. that focus on laser projection and laser television.
The HL63283HD is a visible wavelength laser diode in a 9-mm diameter CAN package with high heat dissipation and a high wall plug efficiency of 40 percent. It offers 1.2-W optical
output power at a typical center lasing wavelength of 637 nm at 25 °C. Its operating temperature range is −10 to 45 °C, with a typical operating voltage of 2.3V, a 2V LD reverse with a typical threshold current of 340 mA and an operating current of 1300 mA. The typical beam divergence parallel to the junction is 10° and perpendicular to the junction is 33°.
The HL63290HD is also a visible wavelength laser diode in a 9-mm diameter CAN package with high heat dissipation and high wall plug efficiency of 40 percent. However, it offers a higher continuous-wave optical output power of 2.2 W at a typical center lasing wavelength of 638 nm at 25 °C. Its operating temperature range is −10 to 55 °C, with a typical operating voltage of 2.4V, an LD reverse voltage of 2V with a typical threshold current of 600 mA and an operating current of 2.4 A. The typical beam divergence parallel to the junction is 10° and perpendicular to the junction is 33°.
