“…Pulsed, tunable 2 µm sources laser have been developed [3,4] but they require complex alignment or do not have narrow line-width emission and they exhibit relatively long pulses. For this purpose we fisrt built a CW 2 µm Tm:YAP laser with a transversally chirped volume Bragg grating (TC-VBG) to narrow the spectrum and perform wavelength tuning [5]. To pump the OPO, ~250 µJ pulses of 10-100 ns are targeted.…”
A pulsed, narrow-linewidth, wavelength-tunable Tm:YAP laser was realized. 1 kHz stable operation with 200 µJ, 50 ns pulses is reported. Spectrum was narrowed to 0.2 nm and tuned from 1940 to 1960 nm with a transversally chirped volume Bragg grating.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
