Narrow Linewidth Tunable Solid-State Microchip Lasers for Precision Inertial Navigation Systems (PINS)

Abstract

In Phase 1 of the PINS program we were able to demonstrate a multimode operating Cr:LiCAF miniaturized laser generating up to 300 mW of output power. In addition we developed a filter that enables tuning over 0.9 nm and single-mode operation. Initial demonstrations with test devices showed single-mode operation up to 20mW of output power with linewidth on the order 5MHz. We are confident, that further development could bring the single mode output power beyond 150mW and the linewidth well below the 100kHz level and with additional effort into the Hz range. We have also demonstrated significant index changes in GaP wafers by carrier injection, which can be used later for fast phase modulation in the laser potentially with GHz modulation speed.
