PULSE STABILIZATION DEVICE OF A FIBER TYPE FEMTO SECOND LASER CAPABLE OF CONTROLLING THE DISTANCE BETWEEN THE SATURABLE ABSORBER OF A FEMTO SECOND LAYER AND AN OPTICAL FIBER CONNECTOR AND A METHOD THEREOF

摘要

PURPOSE: A pulse stabilization device of a fiber type femto second laser and a method thereof are provided to obtain stabilized laser pulses by automatically executing a locking mode.;CONSTITUTION: A fiber type femto second laser system comprises a pump laser (100), a fiber resonator (200), and a distance controller (300). The distance controller controls a distance (d) between a saturable absorber and an optical fiber connector. The distance controller comprises a base (360), a first fiber (210), a second fiber (320), a moving unit (330), and a driving unit (340). The second optical fiber holds the saturable absorber. The moving unit relatively moves the base in order to control the distance between the saturable absorber and the first fiber. The driving unit relatively moves the moving unit.;COPYRIGHT KIPO 2013;[Reference numerals] (500) Detector; (600) Operation controller unit; (800) Display unit
