World’s first watt-level high-output photonic crystal laser
In conjunction with Kyoto University’s Photonics and Electronics Science and Engineering Center, Hamamatsu Photonics has developed what it claims to be the world’s first watt-level photonics crystal laser, a next-generation semiconductor laser light source.
The group successfully demonstrated continuous room temperature operation of the laser, which generated output of 1.5W while maintaining a narrow beam spread of less than 3°. The group also demonstrated the utility of the laser’s high brightness and high output by showing how it can burn through a substance through direct, lens-less irradiation.
These results are a significant milestone for laser-based manufacturing, as they lay the groundwork for the future adoption of this type of laser for laser excitation, wavelength conversion, biotechnology, analytical chemistry, and other applications.
Portions of this research were supported by grants from the Japan Science and Technology Agency’s ACCEL Program and from the Photon Frontier Program of Japan’s Ministry of Education, Culture, Sports, Science, and Technology.
