High power diode end pumped slab MOPA system
Abstract
A diode laser pumped amplifier based on multipass configuration was proposed. The proposed high power diode end pumped slab master oscillator power amplifier (MOPA) system combined the properties of high quality lasers with high output power. A slab shaped Nd:YVO4 crystal was end pumped by a four bar diode laser stack. It was found that output power of the system could be efficiently scaled by pumping crystal from two sides, increasing number of passes and enlarging crystal width in unstable direction.
