SMALL-SIZED FIBER LASER DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a small-sized laser device which has both a laser oscillator to output optical pulses and a laser amplifier. SOLUTION: A small-sized fiber laser device has a laser oscillator connected to a laser beam source 88 for generating optical pulses and a laser amplifier connected to the laser oscillator for amplifying the generated optical pulses. The laser oscillator has a first optical fiber 42 which connects bulk parts to the laser beam source 88, and the laser amplifier 14 has a second optical fiber 62 which connects the bulk parts to a laser light source 92. The first and the second fibers 42 and 62 are wound around a common holder. A fiber tray is connected to a fiber bench, and the bulk parts of the laser oscillator and the laser amplifier are attached to the fiber bench.
