Paper Abstract

A compact Nd:YAP solid-state oscillator/amplifier laser system with a possibility of fast wavelength switching from 1.34 micrometers to 1.08 micrometers and with a reliable flexible radiation transport device was developed. The laser oscillator was composed of two rear mirrors, inner for 1.34 micrometers and outer for 1.08 micrometers generation. An output resonator mirror was common to both wavelengths. A crystal of V3+:YAG was used as a passive mode-locker at 1.34 micrometers Nd:YAP laser transition, and BDN II foil served as a saturable absorber at 1.08 micrometers laser wavelength. Both resonators were separated by a mechanical shutter. A single flashlamp oscillator-amplifier cavity configuration was utilized in order to keep the device compact and small in dimensions. At the output, either a train of 1 nsec long 1.3 micrometers pulses with the energy up to 30 mJ, or 20 nsec long 1.08 micrometers giant pulses with the energy up to 100 mJ were generated. A cyclic olefin polymer-coated silver hollow glass waveguide with the optimal coupler was used for the radiation delivery. The measured transmission for 1m long waveguide reached 93 percent and 80 percent for 1.34 micrometers and 1.08 micrometers , respectively. This alternative double- wavelength system can be suitable for medical or industrial applications.
