Narrow spectral bandwidth tunable pulsed solid-state laser system

摘要

A tunable solid-state laser system whose bandwidth and wavelength are controlled by the injection of light from a semiconductor diode laser. This laser system is capable of providing output light pulses over substantially all wavelength ranges in the electromagnetic spectrum. When suitably configured, it creates wavelength tunable (or fixed wavelength) pulses having spectral bandwidths that are Fourier transform limited and wavelength stabilized. The coupling means between the semiconductor diode laser and the ring laser cavity incorporates a means for optically isolating the diode laser source from optical feedback from the ring laser, ensuring diode laser source stability.
