“…Over the past decade, there has been significant development of high power ultrashort pulse lasers with high repetition rate [1][2][3], with applications including nonlinear optical frequency conversion, precise material processing, satellite ranging, and high-intensity physics [4][5][6][7]. Specifically, in ultrashort lasers in the order of picoseconds, their pulse width is smaller than the electron-phonon coupling time of most materials, heat conduction can be decreased substantially during the process of interaction.…”

A non-pulse-leakage optical fiber pumped 100-kHz level high beam quality Nd:YVO 4 picosecond amplifier has been developed. An 80 MHz, 11.5 ps mode-locked picosecond laser is used as the seed with single pulse energy of 1 nJ. By harnessing the double β-BaB 2 O 4 (BBO) crystal Pockels cells in both the pulse picker and regenerative amplifier, the seed pulse leakage of the output is suppressed effectively with an adjustable repetition rate from 200 to 500 kHz. Through one stage traveling-wave amplifier, a maximum output power of 24.5 W is generated corresponding to the injected regenerative amplified power of 9.73 W at 500 kHz. The output pulse duration is 16.9 ps, and the beam quality factor M 2 is measured to be 1.25 with near-field roundness higher than 99% at the full output power.

“…High-power laser is of great interest for inertial confinement fusion [1][2][3], industrial processing [4,5], optoelectronic countermeasures [6], strong-field physics [7,8], and scientific research [9][10][11][12]. As an important factor related to the beam quality, a uniform wavefront is conducive to maintaining the high quality spatial distribution in propagation.…”

Abstract:We demonstrate a method for wavefront distribution compensation with a low-cost small-aperture deformable mirror in the front stage of a complex high-power solid-state laser system. Meanwhile, an iterative algorithm for improving wavefront quality is indicated. Using this method, the wavefront compensation was studied in our single-shot high-power laser system that operated with and without the main amplifiers, respectively. The wavefront was compensated effectively, showing the near-flopped-shape output with the peak-to-valley value of 0.29 λ and root meam square (RMS) of 0.06 λ at 1053 nm.
