Abstract: 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.

Abstract: PURPOSE: A minute particle detecting device is provided to detecting scattered lights caused by minute particles in which spill lights is maximally excluded by controlling a focus of lights irradiated on the minute particles to be arranged between an intake unit and a beam blocking unit. CONSTITUTION: A minute particle detecting device(100) comprises an optical element, a collecting optical system, a particle flow path, a beam blocking unit(140), a condensing lens, and a detector. The collecting optical system arranged in a direction where lights emitted from the optimal element are progressed, thereby collecting the lights. The particle flow path is arranged in a direction where lights penetrated through the collecting optical system are progressed and formed to be crossed the lights. The beam blocking unit secludes lights penetrated through the particle flow path. The condensing lens is arranged in the rear part of the beam blocking unit. The detector is arranged in the rear part of the condensing lens, thereby detecting lights scattered by the particles. A focus formed by the optical element and collecting optical system is arranged in the rear part of the particle flow path.
