China unveils world’s first deep UV laser device

China has become the first country in the world to possess Deep Ultraviolet (DUV) solid-state laser device. The device was launched by the Chinese Academy of Sciences (CAS) after its successful testing. The device marks the world’s first-ever output of 1,064-nanometer’s 6-harmonic frequency multiplication, shortening the diode-pumped solid-state laser (DPL)’s wavelength to 177.3nm.

What can be the use of Deep Ultraviolet (DUV) solid-state laser device?

The device can be used to enhance the production of grapheme, superconductors, insulators and catalysis. The device which uses Potassium Beryllium Fluoroborate (KBBF) prism coupling device-based DPL source features a smaller size, higher energy resolution and higher photon influx density.
