摘要： A laser beam LB, which has entered a housing, travels via a reflection mirror and through a beam diffusion plate, ND filters 42 and a visible rays cut-off filter 44 to impinge on a beam receiving surface of a photodiode 46. A resistance heating element 48 in the form of, e.g., a metal film resistor and a power transistor 50 for the supply of electric power to the resistance heating element 48 are fixedly secured by bolts via respective insulating sheets with thermal conductivity to external wall surfaces of thick sidewalls 28d and 28e of a thermally conductive second retainer 28. The second retainer 28 is heated by both heat generated by the resistance heating element 48 and heat generated by the transistor 50. The second retainer 28 is provided also with a temperature sensor 52. A temperature control circuit accepts an output signal from the temperature sensor 52 and provides control of an output signal from the transistor 50 so as to allow the temperature of the second retainer 28 to conform to a set temperature.

摘要： A KTP crystal is irradiated by a long-pulse fundamental wave pulse laser beam having a pulse width of 100 μs or longer typically output from a solid-state pulse laser such as a YAG pulse laser. In the KTP crystal, wavelength conversion is performed to generate a second harmonic pulse laser beam with a two times higher frequency, which long-pulse second harmonic pulse laser beam is in turn output for laser processing such as welding etc.

摘要： A laser beam-splitting apparatus that is capable of producing a plurality of split laser beams having a uniform laser output as well as easily and precisely adjusting the laser output of the individual split laser beams to any desired value. The apparatus is provided with one or a plurality of partial reflection and transmission mirrors each having a reflectance and transmittance which spatially and continuosly varies in one-dimensional or two-dimensional directions for the wave length of the primary laser beam. The reflectance and transmittance of each mirror for the laser beam incident thereon can be adjusted to a desired value by an adjusting device which is adapted to the position of the mirror. The laser beams reflected or transmitted from the reflection and transmission mirrors are output as the split laser beams respectively.
