Energy-Transfer Upconversion and Thermal Lensing in High-Power End-Pumped Nd : YLF Laser Crystals
Thermal lensing in an end-pumped Nd : YLF rod, under lasing and nonlasing conditions, has been investigated. Under lasing conditions, a weak thermal lens, with dioptric power varying linearly with pump power, was observed. Under nonlasing conditions, where higher inversion densities were involved, hence relevant to Q-switched operation or operation as an amplifier, a much stronger thermal lens ...
متن کاملDiode-Pumped High Energy and High Average Power
We present our research on the high energy picosecond laser operating at a repetition rate of 1 kHz and the high average power picosecond laser running at 100 kHz based on bulk Nd-doped crystals. With diode-pumped solid state (DPSS) hybrid amplifiers consisting of a picosecond oscillator, a regenerative amplifier, end-pumped single-pass amplifiers, and a side-pumped amplifier, an output energy ...
متن کاملCompensation of strong thermal lensing in high-optical-power cavities.
In an experiment to simulate the conditions in high optical power advanced gravitational wave detectors, we show for the first time that the time evolution of strong thermal lenses follows the predicted infinite sum of exponentials (approximated by a double exponential), and that such lenses can be compensated using an intracavity compensation plate heated on its cylindrical surface. We show th...
متن کاملDiode-end-pumped passively mode-locked high-power Nd:YVO4 laser with a relaxed saturable Bragg reflector.
We demonstrate a high-power passively mode-locked Nd:YVO (4) laser that uses a saturable Bragg reflector (SBR) with strain relaxation. 23.5 W of average power with ~21.5-ps cw mode-locked pulse trains was generated at a 50-W pump power. Experimental results show that appropriate strain relaxation in the SBR makes the mode-locking operation less sensitive to temperature variation.
متن کاملEfficient high-power diode-end-pumped TEM(00) Nd:YVO(4) laser with a planar cavity.
We demonstrate a compact and efficient diode-end-pumped TEM>(00) laser with output power of 30 W for 48 W of incident pump power by use of two coated Nd:YVO> (4) crystals to form a thermally stabilized flat-flat cavity. In Q -switched operation 25 W of average power at a pulse-repetition rate of 100 kHz and ~0.9-mJ pulse energy at a pulse-repetition rate of 10 kHz were produced.
