An actively mode-locked/Q-switched Nd:phosphate glass laser oscillator

Good stability and reliability is achieved in the operation of a laser oscillator with Nd-doped phosphate glass that is actively mode-locked, as well as actively <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Q</tex> -switched. It delivers a single pulse at 1.053 μm with an energy of 140μJ. Pulse duration is variable between 150 ps and 1.1 ns. The system offers a TTL trigger well related to the Single pulse.
