“…In recent years, high-peak-power picosecond lasers have been used in a variety of scientific and technological applications, such as time-resolved nonlinear laser spectroscopy [1][2][3], laser ablation and micromachining [4,5], picosecond optical parametric amplifiers pumping [6], photo-guns equipped in electron accelerator injectors [7,8], precise satellite [9,10] and lunar [11,12] laser ranging, laser driving wide-band high-power semiconductor switches [13,14], coherent anti-Stokes Raman microscopy [15], two-photon bioimaging [16], aesthetic cosmetology and dermatology [17,18] and clinical surgery [19,20]. Then, practical and reliable, highly stable and compact picosecond laser schemes providing single pulse energy of mJ and multi-mJ levels operating at different repetition rates, typically within kHz, are widely required.…”
