Co Spinel Co2+ MgAl2O4 Crystal For High Power Laser
Introduction:
Co:MgAl2O4,(Cobalt-doped magnesium aluminate spinel ) allow the generation of short nanosecond pulse with high peak power around the eye-safe wavelength of 1.5um,perfect for telemetry applications.
The absorption spectrum of Co2+-doped MgAl2O4 exhibited a broad absorption band in the wavelength range of 1200–1600 nm, which indicated that Co2+ ions substituted for the tetrahedrally coordinated Mg2+ ions in the MgAl2O4 lattice. Passive Q-switching of solid-state lasers with solid-state saturable absorbers is a very attractive Q-switching technique because it allows to develop compact and low cost laser sources of nano and sub nanosecond pulses far various applications
Features:
Suitable for 1540 nm eye-safe lasers
High absorption section
Negligible excited state absorption
High optical quality
Uniformly distributed Co
