Single Longitudinal Mode (SLM) lasers are of interest for various coherent LIDAR techniques that utilize the Doppler wavelength shifting effect. Also, narrow linewidth lasers are of interest for Differential Absorption LIDAR (DIAL) which can precisely identify trace chemical species. However, such SLM lasers are often limited to low (~100Hz) rep rates due to laser seeding limitation. We report the development of a seeded SLM technology that enables us to achieve up to 85W of power at 1064nm with a linewidth less than 100 MHz. Furthermore, such SLM powers can be realized at rep rates up to 10 kHz enabling a myriad of next generation of narrow linewidth laser applications. We have built both watercooled and air-cooled versions of theses SLM lasers for various power level requirements.
