    Abstract: PROBLEM TO BE SOLVED: To provide a compact amplifier of a high energy and super short light pulse. SOLUTION: This system is achieved by a light pulse amplification and emission system consisting of a pump light source 100 which generates a light pump pulse having a preliminarily dertermined wide, a signal light source 130 generating a light signal pulse, a combining optical system 160 which receives the light pump pulse and the light signal pulse to combine them and is for supply the combined light pulses, a parametric amplifier 170 which is consisting of a quasi-phase-matched crystal amplifying the light signal pulse by using the energy of the light pump pulse while receiving the combined light pulses and an application unit which receives the amplified output of the amplifier and applies it to a clearly expressed position. Preferably, this system is composed of a chirped pulse amplification and emission system consisting of the light pulse amplification and emission system and a compressor 180 which receives the light signal pulse amplified in the parametric amplifier and compresses it.

    Abstract: PROBLEM TO BE SOLVED: To provide a method of stabilizing a short pulse fiber laser which reduces a timing jitter caused by a variation in environmental condition such as vibration, air disturbance, a change in temperature to a minimum. SOLUTION: The method of stabilizing a short pulse fiber laser has a segregating step which segregates the fiber lasers 210 and 220 from an outside environment, a winding step which winds the fiber lasers 210 and 220 around a fiber spool 280, and an operating step which operates the fiber lasers 210 and 220 while the fiber lasers 210 and 220 are wound around the fiber spool 280. The fiber lasers 210 and 220 are wound around the fiber spool 280 and segregated from the outside environment, and therefore become free of influences of the variation in environmental condition and are stabilized.

    Abstract: PROBLEM TO BE SOLVED: To provide a means transmitting a very short light pulse with a high peak power to a required point in an optical device. SOLUTION: This very short light pulse transmitting device is provided with a pulse expander 20 receiving the super-short light pulse with a high peak power and expanding its pulse width and an optical fiber 30 transmitting the light pulse over a required distance and having the dispersion compensating other dispersion so that the light pulse is re-compressed sufficiently in the required point in the optical device 50. The pulse width of the light pulse is expanded by the expander 20, and a chirp light pulse with a low peak power is formed. Thus pulse whose dispersion is compensated while it is transmitted through the optical fiber 30, and is re-compressed by the optical fiber 30 or a compressor 40 to be transmitted to the optical device 50. Since the peak power in the optical fiber 30 is small, the super-short light pulse hardly by affected by a nonlinear effect.
