Abstract

A compact, high energy and high repetition rate microchip laser platform with tailorable parameters for a wide range of novel sensing applications is presented. The source provides tunable pulse repetition rates from 1 - 200 kHz. The pulse duration can be tailored to cover 100 ps to nanosecond-range at 1064 nm, and sub-ns to several ns at 1535 nm. The highest pulse energy directly from the compact seed laser is 12 µJ, for 1 kHz operation and 1535 nm, making it very attractive for long-range eye-safe sensing applications. The 1064 nm, 100 ps laser source can provide up to 2 kW of peak power at 150 kHz making it attractive for high-resolution LIDAR applications. The microchip architecture allows for an extremely compact footprint enabling high durability and operation in extreme environmental conditions.
