Abstract

Self-starting cw mode locking of a $888\mathrm{nm}$ pumped high-power $\mathrm{Nd}\text{:}{\mathrm{YVO}}_4$ laser using the ${\chi }^2:{\chi }^2$ cascaded Kerr lens in lithium triborate without exploiting the “nonlinear mirror” technique is presented. The nonlinear loss modulations are mainly provided by a soft aperture mechanism in the gain medium. A high average output power up to $15.4\mathrm{W}$ at $10.8\mathrm{ps}$ pulse duration and short pulses down to $5.7\mathrm{ps}$ at $11.4\mathrm{W}$ have been achieved.
