Paper Abstract

A diode-pumped passively Q-switched Nd:YVO4 laser operating at 914nm is demonstrated. The solid-state laser is quasi-continuously pumped at 808nm using a 35W fiber-coupled diode laser. Several Cr4+:YAG saturable absorbers with different outcoupling coefficients are utilized to optimize the overall system performance. The simple two component cavity design reduces the system complexity and enables efficient pump power conversion along with long-term stability concerning power and wavelength. Furthermore, temperature dependent stimulated-emission cross-section in the Q-switched regime is investigated by observing the evolution of the single pulse energy over a temperature range of 70 K.
