What are the main features of the LD bar developed by Hamamatsu Photonics?

It achieves a world-class quasi-continuous wave output of 2.0 kW at room temperature from a 1 cm wide LD bar, surpassing previous records.

What fields can this LD bar technology be applied to?

It is expected to be applied to industrial laser processing equipment and as excitation light sources for solid-state lasers. Future expansion into advanced fields requiring high-energy light sources is also anticipated.

What was the background of this research and development?

It was conducted under consignment from the "Pioneering Research Program / Frontier Development Business" of the National Institute of Advanced Industrial Science and Technology (NEDO).

What kind of emission method is "quasi-continuous wave"?

It is an emission method that repeatedly outputs light intermittently for short durations at high speed, possessing characteristics intermediate between continuous wave and pulsed emission.

When and where is this achievement scheduled to be announced?

It is scheduled to be presented at "The 30th International Semiconductor Laser Conference 2026" in Finland, starting June 14, 2026.
