“…This technique is similar to KLM, but it utilizes second order nonlinearity, whose sign and magnitude are easily controlled by phase mismatched conditions of a SHG crystal [1]. The higher damage threshold of SHG crystals and their lower residual absorption in comparison with SESAMs enable operation at high average power, which is limited by the maximum one achievable in continuous-wave (CW) TEM 00 output [2,3]. However, it was demonstrated manly for Nd-doped crystalline lasers.…”

“…Mode-locked lasers are promising devices for synthesis of high purity microwaves in sub-GHz and GHz range [1]. Solid-state lasers based on Nd:YVO 4 gain medium with intracavity frequency doubling have previously demonstrated reliable self-starting regime of mode-locked operation which has been explained by the Kerr nonlinearity in the active medium [2,3], cascaded χ (2) lens process and nonlinear mirror formed by the doubling crystal and an output coupler (OC) [4,5]. In this Letter we report on a transition between two mode-locked states with different repetition rates which is entailed by repetition rate splitting.…”

Herein, we report on the mathematical modelling and experimental study of the regime of nonsoliton mode locking in a laser based on the Yb3+:LuAlO3 (Yb:LuAP) crystal with longitudinal pumping by laser diode radiation. Simulation based on the Haus master equation permitted to determine the requirements for the parameters of a saturable absorber (SA), the level of the average output power, the size of the TEM00 mode of the cavity in the active element and on the gate to obtain a stable regime of generation of picosecond laser pulses. Laser experiments were carried out in a fourmirror X-shaped resonator using a semiconductor saturable mirror (SESAM) as a passive modulator and a laser diode with a fiber output of a maximum power up to 30 W at a wavelength of 978.5 nm as a pump source. We obtained a stable passive mode locking with a maximum average output power of up to 12 W and an ultrashort pulse duration of about 2 ps at an optical conversion efficiency of pump radiation into lasing radiation of about 38 %. Laser pulses were obtained at a central wavelength of about 999 nm with a minimum Stokes shift (about 2 %) with respect to the pump radiation, which significantly reduced the thermal load on the active element. Additionally, the preliminary results on the second harmonic generation and synchronous pumping of a parametric light generator using a Yb3+ : LuAlO3 crystal laser as a pump source are presented.
