Pulsed neodymium glass laser system for investigating nonlinear optical phenomena in gases
Abstract
A powerful frequency-tunable neodymium glass laser active mode-locked laser system is described. Near-complete mode locking is provided by periodic Q-modulation of the resonator in combination with spectral selection of longitudinal types of oscillation. Preliminary findings from experiments in generating the seventh harmonic in mercury vapor are cited. The output parameters of the laser satisfy the conditions for experiments on generating higher harmonics of the fundamental radiation. The pulse length of the periodic Q-modulated laser is independent of the spectrum width of the radiation generated in the band extending from several tens to several tenths of a centimeter. The periodic Q-modulation scheme can be used for active mode locking.
