Self-Injection-Locked, Narrow-Line Laser

Cygnus Laser proposes to develop a narrow linewidth laser source ideal for use in airborne lidar atmospheric studies. This laser will provide higher output energies than existing systems directly from a single flashlamp pumped oscillator, yet will have suitable spectral linewidth and stability for lidar. The tuning range will be from 800 nm to 960 nm, covering the ranges required for water vapor lidar. When the third harmonic of the laser output operating from 850 nm - 930 nm is generated, atmospheric ozone can be sensed. All wavelengths and linewidth specifications without the use of separate diode injection seeders. In the commercial marketplace, this laser would be a direct replacement for the doubled Nd:YAG pumped Titanium Sapphire laser, with a significantly lower overall cost.
