“…For obtaining the shorter pulse width and higher peak power ps pulse laser at 1.34 μm, mode-locked and regenerative amplifier (RA) technologies are under consideration. There are several reports on CW mode-locked pulses using intracavity semiconductor saturable absorbers (SESAM) or relying on a sequence of two elementary second-order nonlinear processes at 1342 nm [10]- [12]. For example, Li et al demonstrated a 2.3 W passively mode-locked 1342 nm Nd:YVO 4 laser with a pulse width of 29.2 ps at 76 MHz using a SESAM [10].…”

“…Lenhardt et al reported on a 6.5 W parametric Kerr-lens mode-locked 1342 nm Nd:YVO 4 oscillator using cascaded second-order nonlinearities in LBO at PRR of 143.5 MHz with pulse width of 10 ps. This leads to a pulse energy of 45 nJ and a peak power of 4 kW [12]. Most pulse energy and peak power obtained directly from the mode-locked lasers were very low due to the high repetition rate of megahertz order.…”

We report on a high energy, high peak power 1342-nm Nd:YVO 4 picosecond (ps) regenerative amplifier under 880-nm laser-diode (LD) in-band pumping operating from 1 to 10 kHz. The maximum average output power of 1.62 W was obtained with the repetition rate of 10 kHz and the pulse width of 44.9 ps. The corresponding pulse energy and the peak power were up to 0.162 mJ and 3.61 MW with a total optical gain as high as 6.5 × 10 5 . The laser beam quality factor of M 2 was measured to be 1.75 at the full output power. The maximum pulse energy of 0.243 mJ and the maximum peak power of 5.55 MW were obtained at 1 kHz, resulting in its total optical gain of 9.7 × 10 5 . This is the highest pulse energy and the highest peak power for LD-pumped high-beam-quality 1342-nm ps lasers with kilohertz repetition rate reported to date.Index Terms-High energy, high peak power, picosecond, regenerative amplifier, 1342 nm.

A high average power 1342 nm passively CW mode-locked picoseconds (ps) composite Nd:YVO4 laser was demonstrated with a semiconductor saturable absorber mirror (SESAM). The oscillator cavity was carefully designed to optimize the laser beam radii in the crystal and on the SESAM. The combination of composite bonded laser crystal, direct pumping, and dual end-pumped configuration was adopted to reduce the thermal effect and produce high output power with high beam quality. A maximum average output power of 7.63 W was obtained with a repetition rate of 77 MHz and a pulse duration of 24.2 ps under an absorbed pump power of 38.6 W, corresponding to an optical-optical efficiency of 19.7% and a slope efficiency of 25.9%, respectively. The beam quality factor M(2) was measured to be 1.49.
