摘要： PROBLEM TO BE SOLVED: To obtain a pulse gas laser which is capable of easily varying pulses in width by tens of ns without changing a discharge circuit and a laser tube. SOLUTION: A cavity damping system of stable resonator structure provided with a reduction optical system is provided to an oscillator to control pulses in width. A multi-path amplifying optical system is provided to an amplifier so as to extract short pulse laser rays efficiently. That is, the oscillator stores laser rays in a stable resonator composed of total reflecting mirrors 8 and 16, and an EO device 14 is switched to chop up a laser beam. The four-path optical system of the amplifier is composed of a polarized beam splitters 29 and 36, a Faraday rotator 30, and total reflection mirrors 37 and 32. By this setup, an oscillator is set variable, and a pulse laser gas device of this constitution can be improved in efficiency matching the pulse width of laser rays with the gain time width of the amplifier.

摘要： PROBLEM TO BE SOLVED: To automatically detect a leak of oil without setting special environment by exciting a leak of oil to emit light and selecting the fluorescence wavelength and light emitting time thereof to observe them. SOLUTION: The pulse laser beam 2 from a pulse laser apparatus 1 is introduced into a fiber cable 3 by a lens 4 and introduced into an irradiation head 7 through a cable 3. The emitted laser beam 2 from the head uniformly irradiates a monitor region 6 in a pulse like state. By this constitution, the leak of oil 8 generated from machinery 5 emits fluorescence which is, in turn, appropriately selected by a wavelength selection element 9 to be transmitted. A camera controller 11 opens the shutter function of an image sensor 10 immediately after the extinction of laser beam 2 according to the signal from a synchronizing signal wire 12 to open the same for a preliminarily prescribed time before closes the shutter. As a result, an image signal is applied to a calculator 13 through the controller to be processed to judge the leak of oil and an alarm 14 emits a warning. By this constitution, the leak of oil can be automatically detected.

摘要： PURPOSE:To prevent an irradiation efficiency due to the whitening of a reaction product from becoming low, and enhance the irradiation efficiency. CONSTITUTION:A reaction container 1 is held in freely rotatable manner and a doughnut-like recovery container 5 is provided in such a manner that the top opening of the reaction container 1 is covered by the container 5. In addition, above the recovery container 5, a supply line 10 for liquid to be treated 9 which supplies the liquid into the reaction container 1, and a total reflection mirror 12 which projects a light beam 11 are provided. The reaction product precipitated in the liquid to be treated 9 by irradiation with the light beam 11 is pushed to the periphery by centrifugal force of the reaction container 1, and the reaction product decreases in the center of the reaction container 1. Further, the irradiation efficiency is no longer reduced by the reaction product sticking to the inner surface of the reaction container 1 by irradiating with the light beam 11 from a free liquid level. Thus, stabilizing the irradiation process is achieved.
