摘要： PROBLEM TO BE SOLVED: To provide a pulse laser beam machining device capable of sufficiently preventing the damage of an optical transmission medium. SOLUTION: The pulse laser beam machining device 100 for machining a workpiece 4 by irradiating the workpiece 4 with a femtosecond pulse laser beam by the optical transmission medium 3 is equipped with a light source 1 for making the laser beam incident on the optical transmission medium 3 and an optical system 5 for condensing the laser beam emitted from the medium 3 to the workpiece 4. The medium 3 includes an optical fiber 20 and refractive index changing sections 21 and 22 disposed at both ends thereof. The laser beam is made incident on the refractive index changing section 21 and is emitted from the refractive index changing section 22. In the refractive index changing section 21, the refractive index changes along the direction toward the optical fiber 20 from the refractive index changing section 21 so as to approximate from the refractive index n 1 of air to the refractive index n 2 of a core 23 of the optical fiber 20. In the refractive index changing section 22, the refractive index changes along the direction toward the changing section 22 from the optical fiber 20 so as to approximate from the refractive index n 2 to the refractive index of water 6.

摘要： PROBLEM TO BE SOLVED: To provide a high-speed particle generator which can generate high-speed particles efficiently by monitoring the state of the generation of them in real time.
SOLUTION: A target 30 located in a vacuum chamber 60 is irradiated with laser light L1 outputted from a laser light source 10 while the laser light L1 is condensed by a condensing optical system 20. Consequently, the high-speed particles P including protons are generated and emitted from the target 30. Moreover, a plasma luminescence L2 from the target 30 resulting from the condensation and irradiation with the laser light L1 is measured by a light measurement device 40 and the measured signals are analyzed by an analyzer 50 to evaluate the state of the generation of the high-speed particles P. Subsequently, a mechanism 25 for moving the optical system is controlled on the basis of the results of the analysis, the condensing optical system 20 and the target 30 are controlled through a mechanism 35 for moving the target 30 for the feedback control over the state of the generation of the high-speed particles P in the target 30.

摘要： PROBLEM TO BE SOLVED: To provide a far IR light generator capable of easily controlling the wavelength spectra of far IR light. SOLUTION: The far IR light generator is comprised of a laser light source 1 for supplying the pulse exciting light used for generation of the far IR light and a far IR light generating section 4 having a nonlinear optical crystal 40. The generator makes the exciting light from the laser light source 1 incident on the crystal 40 and generates the far IR light by an optical rectification effect. Also, a polarization control section 3 having a polarization control element, such as a half-wave plate, is installed in an optical guiding unit 2 from the laser light source 1 to the far IR light generating section 4. The wavelength spectra of the far IR light generated in the nonlinear optical crystal 40 are controlled by controlling the polarization state of the exciting light in the polarization control section 3.
