Abstract: A method for generating ultra-short pulse amplified Raman laser light. Short pulse laser light is amplified, and a portion thereof is introduced into a Raman oscillator to produce compressed laser light. The compressed light is introduced to a first Raman amplifier. The remainder of the short pulse laser light is introduced to a polarizer, and the reflected light is introduced into the first Raman amplifier to pump it. The light transmitted through the first Raman amplifier that has not contributed to pumping is introduced to a beam splitter to produce a second reflected light that is passed to a second Raman amplifier to pump that amplifier. The compressed light is amplified in the first Raman amplifier and introduced to the second Raman amplifier to further amplify it. This further amplified radiation is passed through delay lines to the beam splitter, which passes only first Stokes radiation to generate ultra-short pulse amplified Raman laser light.

Abstract: Short-pulse Raman laser is used to perform precision working of a substance without causing thermal effects on it or examine the interior of the skin or process the interior of a transparent material such as glass. By typically choosing a suitable Raman medium to be illuminated with a pump laser, the short-pulse Raman laser can have a wavelength that matches the wavelength of absorption by the substance of interest.

Abstract: The efficiency of wavelength conversion of laser light can be improved by allowing incident laser light to pass through nonlinear optical crystals a multiple of times. In converting the wavelength of laser light to generate second- and higher harmonic waves, a returning mirror, a polarizer and nonlinear optical crystals are combined and the rotation of polarized light is utilized to allow the incident laser light to undergo multiple passes through the nonlinear optical crystals so that it can be converted in wavelength with higher efficiency.

Abstract: The wavefront of laser light as it propagates through a medium is controlled so that not only the inherent aberrations in the wavefront of the laser light itself but also the aberrations that are progressively caused by passage of laser light through the medium are effectively corrected to achieve long-distance propagation of the laser light through the medium.

Abstract: The compensation amount of the pressure for keeping the index of refraction of the gas constant is calculated on the basis of the pressures and the temperatures that have been measured at different time. Only the pressure of the gas will be varied in accordance with the calculated compensation value of the pressure, whereby the index of the gas can be maintained constant and the oscillation frequency can be kept constant as the consequence. The pressure corresponding to a desired sweeping oscillation frequency is also calculated using the measured pressures and temperatures. The pressure of the gas is varied on the basis of the result of calculation. Synchronously with the variation of the pressure of the gas, the cavity length and the angle of the frequency selecting element are compensated.

Abstract: The improved metal vapor laser capable of cold operation performs plasma etching on a vaporizing metal within a laser tube in the presence of a reactive gas so that the metal is vaporized at temperatures below its boiling point to effect laser oscillation. The laser can be operated at much lower temperatures than a conventional hot-operating version which produces metal vapors by thermal evaporation; in addition, the laser will experience a smaller heat loss while undergoing limited thermal damage to its structural members; further, laser light can be oscillated to produce high output power and, at the same time, the warmup time can be shortened significantly.

Abstract: A method of producing a small expansion of laser light, in a pulse laser apparatus, including producing a small preliminary laser light by pumping a laser medium, and then, after an appropriate time lag, then pumping the preliminary laser medium at a higher intensity than the first pumping, thereby producing a laser light which is smaller in beam expansion than in the case where a preliminary pumping is not performed. The laser light which is smaller in beam expansion is due to the population inversion occurring in a small beam expansion part of pulse laser light obtained by the preliminary pumping.

The laser resonator may also include elements for directing the pumping light onto the laser element at a second additional point thereof. The laser resonator can be used as a laser light source having a wide tunable range with a narrow line width.
