Hamamatsu Photonics has successfully achieved world-class quasi-continuous wave*1 output of 2.0 kW from a 1 cm-wide LD bar at room temperature.

This achievement is expected to expand applications of high-power lasers, including industrial laser processing equipment and pump sources for solid-state lasers, as well as enable future deployment in advanced fields requiring high-energy light sources.

This work was conducted under a project commissioned by the New Energy and Industrial Technology Development Organization (NEDO) as part of its “NEDO Feasibility Study Program / Frontier Incubation Program.” The results are scheduled to be presented at the 30th International Semiconductor Laser Conference 2026, held in Tampere, Finland, starting June 14, 2026, in the session “Workshop Session 1: Advances in Semiconductor Laser Industry.”

 

*1 Quasi-continuous wave (QCW): A mode of operation in which light is emitted in relatively long pulse width such as >100 µs at high repetition rates, exhibiting characteristics intermediate between continuous-wave and ns pulsed operation.
