Yb:CaGdAlO4 (CALGO) for High Power Ultrafast Laser Applications
Electro-Optics Technology
Yb-doped CaGdAlO4 (CALGO) is a very suitable material for high power ultrashort pulse laser applications. Its outstanding properties comprise a high thermal conductivity and an inhomogeneously broadened Yb-emission band caused by the statistical distribution of the Ca2+ - and Gd3+/Yb3+ -ions on the same lattice site.Hence, it offers the ideal combination of glassy and crystalline material properties enabling it to overcome the previous limitations where one usually had to choose between high thermal conductivity (→ high power, crystal) and short pulses (→ statistical dopant distribution, glass).
