Abstract: PROBLEM TO BE SOLVED: To provide glass which allows a large aperture core and/or high doping. SOLUTION: There is included a glass composition which is doped with rare earth and may be used by a rod and an optical fiber of a large core size. The optical fiber and the rod may be used for a fiber laser and a fiber amplifier. The refractive index of the glass may be substantially uniform, or may be close to that of silica depending on the embodiment. Available advantages from the features include the suppression of the formation of an additional waveguide path in a core, thus becoming more important as the size of a core becomes large.

Abstract: PROBLEM TO BE SOLVED: To provide a miniaturized and inexpensive high output chirped pulse amplifier of 100 mW-10 W, and a compressor suitable for the same. SOLUTION: This high output chirped pulse amplifier which generates ultrashort pulses includes a generation source 10 for generating expanded pulses which are expanded pulse lights, an output amplifying stage 20 for amplifying the expanded pulses, the compressor 40 for receiving the expanded pulses from the output amplifying stage 20 to compress them, wherein the output amplifying stage 20 has a double cladding fiber and a pump. The compressor 40 is preferable to have a fiber grid for compressing laser pulse signals into the duration of less than a threshold in a nonlinear effect, and a diffraction grating for accepting pulse signals compressed through the fiber grid in order to further compress the pulse signals. The chirped pulse amplifying action of cladding-pumped fiber allows the chirped pulse amplification of high output to be performed while it is miniaturized and inexpensive.

Abstract: PROBLEM TO BE SOLVED: To provide a porous separator member which is thin, easily manufactured, and manufactured at low cost by arranging separator precursor solution containing a solid granular material and polymer binder at a prescribed ratio on an electrode and changing this separator precursor solution into a porous composite separator to be jointed with the electrode. SOLUTION: A thin layer of separator precursor solution is printed on an electrode surface of an electrochemical battery electrode. Second, the thin layer of the separator precursor solution is vulcanized on the electrode, so as to be changed into a microporous composite separator member. The separator precursor solution is constituted of an ink composed of a solid granular material, dispersed in polymer binder solution dissolved in appropriate solvent. It is preferable to use silica aerosol, which is a main component of a print separator for the solid granular material. In the separator precursor solution, the ratio of the binder to the solid granular material is selected between 5/95 and 50/50.

Abstract: PROBLEM TO BE SOLVED: To provide a small-sized high output chirp pulse amplifier device of 100mW-10W and a compressor suitable for the same device. SOLUTION: This device is provided with a generation source 10 generating an expansion pulse being expanded pulse light, an output amplifier stage 20 amplifying the expansion pulse and the compressor 40 receiving the expansion pulse from the output amplifier stage 20 and compressing it, and the output amplifier stage 20 is provided with a double clad fiber and a pump, and the device is the high output chirp pulse amplifier device generating a super short pulse. The compressor 40 is preferred to be provided with a fiber grating compressing a laser pulse signal to a duration time of a threshold value or below of a non-linear effect and a diffraction grating receiving the pulse signal compressed by the fiber grating for further compressing the pulse signal. By a chirp pulse amplifier action of a clad pump fiber, chirp pulse amplification of a high output though it is miniaturized and inexpensive is made possible.

Abstract: PURPOSE: To stabilize an ultra-short pulse source against environmental variation by reflecting laser energy along an optical axis passing through a gain medium for amplifying the laser energy and outputting the laser energy generated in a cavity. CONSTITUTION: The passively modelocked fiber laser 100 comprises a laser cavity 200, a pump means 300 for injecting laser energy, and a gain medium 202 for amplifying energy in the cavity 200. An energy reflecting means, i.e., a cavity mirror 206, arranged along an optical axis 204 passing through the gain medium 202 reflects a signal light in the cavity 200. The cavity mirror 206 also serves as a laser energy output means for reflecting the laser energy into the laser cavity 200 and passing the remaining laser energy as an output energy.

Abstract: PURPOSE: To provide a method and device for controlling the wavelength of laser radiation using a nonlinear effect. CONSTITUTION: The device relates to a laser beam having a radiation wavelength controlled by a nonlinear effect such as a soliton fiber laser. The radiation wavelength of a laser is generally confined to the center of a gain profile but, by generating a gain control with the use of a nonlinear effect, a comparatively wide bandwidth can be controlled. For example, all nonlinear effects within a laser cavity 200 such as soliton self-frequency fluctuation and cross phase modulation, can be utilized for the purpose of securing a marked gain control and a wavelength adjustment area for a wide bandwidth. As a result, the nonlinear adjustment is achieved.
