ABSTRACT:
A pulse producing mode-locked laser system with only passive lens and filtering elements and low cost Nd:glass laser material, or an equivalent, is stabilized and made to produce reliably output laser pulses of known characteristics and intensity without critical alignment and operating conditions.
This is performed by eliminating response to spurious satellite laser pulses incited when triggering the coherent radiation in the laser materials. Several system components aid in the attainment of the better signal to noise ratio effective in making the laser system produce uniform output pulses from shot to shot, including provision of at least one mirror with a radius of curvature R meeting the criterion 3L>R>L where L is the path length through the laser material between two reflecting mirrors, and a dye mode-locking cell increased in path length by two orders of magnitude to the order of 1 cm. Also the mirrors have a wedge-shaped reflection surface at an angle of .gtoreq.20' up to 2.degree. in order to reflect and eliminate spurious satellite pulse energy out of the reinforcement path axis between the mirrors and through the laser material.
This results in 90% reproducibility of output laser pulse characteristics including profile and intensity.
