Title:
MINIATURIZED LASER AMPLIFIER ARRANGEMENT HAVING A PUMP SOURCE
Document Type and Number:
WIPO Patent Application WO/2011/063777
Kind Code:
A3
Abstract:
The invention relates to a laser amplifier arrangement (19), comprising an optical pump source (21) for emitting pump radiation (6) and an axially arranged laser oscillator-amplifier configuration (24), which can be pumped by the pump radiation (6), wherein the laser oscillator-amplifier configuration (24) comprises a laser oscillator (9), which can be excited by a portion of the pump radiation so as to emit a laser beam (13), and a laser amplifier (23), which is designed to receive both the laser beam (13) and the pump radiation (6) in order to amplify the laser beam (13) by means of the pump radiation (6). In order to increase the power and the beam quality while achieving a high degree of miniaturization, the laser oscillator (9) and the laser amplifier (23) are arranged in a substantially coaxial or collinear manner relative to a longitudinal axis (25) of the laser oscillator-amplifier configuration (24), and the pump source (21) comprises at least one first beam source (1) for producing a first pump radiation to pump the laser oscillator (9), at least one second beam source (2) for producing a second pump radiation (6) for the laser amplifier (23), and a pump radiation conducting device (26), by means of which both the first and the second pump radiation (6) can be lead into the laser oscillator-amplifier configuration (24) substantially in the direction of the longitudinal axis (25) for longitudinal pumping.
