摘要： PURPOSE:To provide a method and an apparatus for removing deposit of a surface with a laser in which the deposit can be removed without damaging the apparatus itself, the removed deposit is scarcely adhered to a lens, etc., the deposit can be efficiently recovered, with less fear of recontamination and the deposit which cannot be removed only with a laser beam can be applied. CONSTITUTION:The apparatus for removing deposit of a surface with a laser comprises a laser oscillator 12 for generating a pulse laser beam 1, a lens system 14 for condensing the beam to a linear focus 2, and a moving unit 16 for relatively moving a surface deposit 3 in a direction perpendicular to the focus to irradiate the deposit, wherein the deposit is removed by ablation. The oscillator is a CO2 laser oscillator, and the pulse laser beam is a high repetition pulse beam having about 1000pps. The lens system is a cylindrical lens having a cylindrical surface.

摘要： PURPOSE:To detect a position highly accurately by arranging a plurality of sensors which converts photo-acoustic waves into electric signal at an optical element which converts a part of the emitted energy of laser light into the photo-acoustic wave, and determining the position of the laser light as the function of the difference in electric signals. CONSTITUTION:Two sensors 14 and 14' are fixed to the rear surface of a total reflection mirror 13 made of copper. Pulse laser light is emitted from a CO2 laser oscillator 10 on the mirror surface of the mirror 13. The elastic wave which has reached each sensor from the laser-light emitting position is converted into a minute electric signal with the sensor. The signals are inputted into AE differential amplifiers 15 and 15'. The difference between two signals from the amplifiers 15 and 15' is operated and further amplified. The signal is inputted into a digital oscilloscope 16 and displayed. Thus, the position of the laser light can be obtained with high sensitivity.

摘要： PURPOSE:To realize multi-beam multi-wavelength type Raman laser oscillation and to obtain a highly efficient and simplified Raman laser system, by constituting only a pair of mirrors within a Raman converter and by applying multi- beam system. CONSTITUTION:In a primary mirror 31 and a secondary mirror 32 which have spot positions on two different circumferences (concentric circle) from the center of a mirror, the primary mirror 31 is provided with input ports A and B each at an arbitrary spot position on each circumference. Similarly, the secondary mirror 32 is provided with output ports (a) and (b) for A and B, respectively for projecting laser beam at a specified number of reflections. Two excitation CO2 laser beams of the same wavelength are input from the primary mirror at the same time, for example, the laser beam input from the input port of the spot position 0 reflects at the spot position 1 of the secondary mirror and is reflected at the spot position 3 of the primary mirror. Thus reciprocating reflections are repeated to project Raman laser of two beams after Raman- conversion before reaching an output port d.
