    摘要： It has been very difficult to accumulate strong laser in the conventional optical resonator, because firstly it has been very difficult to control a resonator length less than 1 Å in resonation position which is required for the laser amplification more than 1,000 times and secondly, the conventional method has utilized laser strength of amplified laser in the optical resonator as the resonance control signal.The present invention provides an optical resonator system to accumulate strong laser. In the system, unamplified modulation wave or harmonic which are derived from oscillation laser are selectively used to tune a resonator length of the optical resonator.

    摘要： Provided is a laser oscillation apparatus capable of stabilizing resonance even when finesse of an optical resonator is increased and generating stronger laser light than that of a traditional apparatus by accumulating laser light in the optical resonator. The laser oscillation apparatus includes a laser light source which generates laser light for excitation, a fiber amplifier which generates laser light with a desired wavelength when the laser light generated at the laser light source for excitation is supplied, an optical resonator, an optical isolator which is interposed between the optical resonator and the fiber amplifier and which guides the laser light from the fiber amplifier to one side of the optical resonator while blocking laser light in the opposite direction, a circulation optical path which accelerates resonance as introducing laser light emitted from the other side of the optical resonator and returning the laser light to the optical resonator via the fiber amplifier and the optical isolator, and a modulator which performs amplitude modulation on the laser light in the circulation optical path.

    摘要： The present invention separates radiation from an object by a polarization filter 3 into polarized light beams, causes one of the beams to enter a spectrum analyzer 7 through a first optical path, causes the other to enter the spectrum analyzer 7 through a second optical path, and measures the two-color ratio, while causes radiation of a blackbody 2 placed in a vacuum ultralow temperature thermostatic chamber 1 in a quasi-thermal equilibrium state at an ultralow temperature in vacuo to enter the polarization filter 3 through a third optical path, separates the radiation into polarized light beams, causes the beams to each enter the same optical paths as the respective optical paths for the radiation of the object, causes the beams to enter the spectrum analyzer 7, measures the two-color ratio, and accurately obtains the temperature of the object on the basis of these two two-color ratios.
