Passively Q-switched microchip lasers are very attractive for various applications because of their sub-nanosecond pulse width, simple and rugged construction and low-cost [1]. We have earlier reported the design of Nd:YAG/Cr4+:YAG passively Q-switched microchip lasers for efficient wavelength conversion from the second to the ninth harmonic [2]. These lasers are useful for spectroscopy, LIDAR, LIBS, materials micro-processing, etc.

A compact UV-light source for MALDI/TOFMS based on an intra-cavity frequency tripled, actively Q-switched ceramic Nd:YAG micro-laser, with more than 55 muJ pulse-energy and less than 5 ns pulse-width up to 6 kHz repetition, has been demonstrated.
