Ushio High Power HL63520HD Red Laser Diodes

HL63520HD Achieved World’s Highest Pulse Optical Output Power of 3.5W

Ushio has released a high-efficiency 638nm laser diode that produces an output power of 2.4W CW / 3.5W pulsed, even in high-temperature environments.

Useful for digital entertainment applications, the HL63520HD has achieved:

  • MTTF of >20,000 hours
  • World’s highest power conversion efficiency of 43%
  • World’s highest optical output power of 3.5W in pulsed operation (maintained over MTTF of <20,000 hours)

The HL63520HD achieves a pulse optical output power of 3.5W 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. It both contributes to increasing the brightness of projectors and reducing the cost of projector light sources.

Ushio laser diodes

Ushio laser diodes offer high output power and high efficiency, enabling increases in projector brightness as well as cost reductions for projector light sources. They additionally contribute to the simplification of the cooling system by reducing overall power consumption.

All Ushio high performance laser diodes are available from the Optoelectronics Company. Please contact the Optoelectronics Company to request samples for testing.



Ushio’s laser diode collection offers wavelengths across UV (375–405 nm), red (630–690 nm), and NIR (705–852 nm), with prospective optical output powers from 5 mW to 3,500 mW. Our LD collection has low and high power lasers, with low-operating currents, long lifespans, and efficiency, all while remaining 100% RoHS-compliant.

Ushio’s Epitex division has grown into the largest collection of light emitting diodes on the market. Covering all violet, visible, and infrared wavelengths, from 365 nanometres (nm) to 1,750 nm, this vast catalogue creates a one-stop-shop for single and multi-wavelength LEDs.
