CW, Q-switched and mode-locking oscillations at 2.1 μm in novel Tm

摘要

:Lu2O3 and others) having an extraordinary long-wavelength 2-μm luminescence band and a high thermal conductivity open up new opportunities for highly efficient laser generation at around 2.1 μm [1]. Transparent laser ceramic materials are attracting great interest as a substitute for the single crystals. Recently, the high-quality sesquioxides ceramics doped by Nd
