Research highlights

1. Passively Q-switched microchip lasers for high peak power generation

Based on Yb:YAG/Cr4+:YAG composite ceramics as gain medium, highly efficient passively Q-switched lasers with pulse width of 237 ps and peak power of over 0.72 MW have been demonstrated for the first time. Details of the research see Optics Express, 15(22): 14516 – 14523 (2007).

Highly efficient passively Q-switched Yb:LuAG microchip laser

Highly efficient, sub-nanosecond passively Q-switched Yb:LuAG microchip laser with Cr4+:YAG as saturable absorber has been demonstrated for the first time, slope efficiency as high as 40% has been achieved. The research on passively Q-switched Yb:LuAG microchip laser has been highlighted on “Photonics Spectra” (January 2008) entitled “Microchip laser exploits Yb:LuAG properties Researchers create passively Q-switched Yb:LuAG laser".
