Tm:YLF slab wavelength-selected laser

A Tm: YLF slab laser was wavelength selected to operate at 1890 nm. The oscillator consisted of a single 2.5% doped Tm: YLF slab, a volume Bragg Grating (VBG) mirror and a 90% output-coupler. The slab crystal was pumped with a 300 W diode stack using a pump reproducing configuration. The output powe...

Description
Summary:A Tm: YLF slab laser was wavelength selected to operate at 1890 nm. The oscillator consisted of a single 2.5% doped Tm: YLF slab, a volume Bragg Grating (VBG) mirror and a 90% output-coupler. The slab crystal was pumped with a 300 W diode stack using a pump reproducing configuration. The output power exceeded 80 W and the beam quality factors in the horizontal and vertical directions were 182 and 2.5 respectively.
