Reliable single-mode operation and fine frequency tuning of a Nd-glass low-gain oscillator

Abstract We present a simple, easily tunable cavity configuration which, by means of two low-loss frequency selectors, is capable of forcing low-gain oscillators to reliably operate in single mode. Its application for tunable (up to 20 nm), 100% single-mode operation of a Q -switched, low gain ( G =2), Nd-phosphate glass laser is discussed.

Development Of An Alexandrite Laser For Spaceborne Lidar Applications

We present the design of a high power, single longitudinal mode and near diffraction limited Q-switched Alexandrite laser. Different experimental solutions, suitable for spaceborne LIDAR applications are examined and critically discussed.

Optical Configurations Suitable For Reliable Single-Mode Operation Of Tunable Vibronic Low-Gain Lasers

We present a comparative experimental investigation of the performance of a number of different frequency selective optical configurations used for line-narrowing of low-gain, solid-state lasers operated in prelasing Q-switched regime. This study has been carried out by paying particular attention to relevant optical problems for the realization of reliable single-mode, tunable, spaceborne, vibronic lasers.
