摘要： PROBLEM TO BE SOLVED: To obtain a device for mutually correcting the degree of coherence which condenses output light to a diffraction limit by making the degree of spatial coherence γSAD and γFAD of both of the TE and TM polarization components of the output light be the same value and by condensing coherence coupled output light with a spherical lens in intensifying the degree of the spatial coherence of two or more laser beams with phase conjugate light via a phase conjugate mirror. SOLUTION: The device is constructed in such a way that output light beams L 1 to L 3 from the semiconductor lasers of a semiconductor laser array are made to be parallel light fluxes with a collimating lens system 15 1 to 15 3 and subsequently laser beams reflected with beam splitters 16 1 to 16 3 are made to be output light L EX and output light beams partly transmitted with the beam splitters 16 are condensed with the spherical lenses 17 1 to 17 3 and are made incident on the phase conjugate mirror 20 with a specified incidence angle. The output light beams L 1 to L 3 contain the mutually perpendicularly intersecting TE and TM polarization components. The degree of condensation of the output light is heightened by making the C axis of a phase conjugate mirror 20 perpendicularly intersect the incidence direction and heightening the degree of spatial coherence of the TM polarization component to the same degree as that of the TE polarization component, to nearly 100%, with the photovoltaic effect of the phase conjugate mirror 20.

摘要： PURPOSE:To provide a double refraction measuring method by which the two-dimensional distribution of double refraction induced in a sample to be measured can be quantitatively measured including the discrimination of the sign (plus or minus) of the relative phase difference with high sensitivity and, at the same time, the direction of a main axis can be recognized. CONSTITUTION:A sample 1 to be measured is set between a circular polarizer 9 and analyzer 5 on the optical path between a monochromatic light source 2 and two-dimensional photoreceptor 8 and parallel rays emitted from the light source 2 are led to the analyzer 5 through the sample 1 after the rays are changed to circularly polarized rays by means of the polarizer 9 while the analyzer 5 is rotated around the axis of the luminous flux. The picture data detected by means of the photoreceptor 8 at regular angular intervals are sampled and fetched to a picture processor 11 of the poststage. Then the relative phase difference caused by the double refraction of the sample 1, the two-dimensional distribution of the double refraction including the sign (plus or minus) of the phase difference, and the direction of the main axis are found by performing arithmetic processing at every pixel based on the picture data.

摘要： PURPOSE:To equalize the spatial distribution of gain while keeping the absorption efficiency of exciting beam high so as to improve the amplification efficiency by reflecting the transmitted light of the LD exciting beam on a 1/4 wavelength plate and linear polarization plate against a solid laser medium based on that a high output LD is linear polarization, to pass the transmitted light through the medium two times without fail. CONSTITUTION:A solid laser amplifier is composed of laser diodes(LD) 1 and 2, collimators 3 and 4, linear polarization plates 5 and 6, and 1/4 wavelength plates 7 and 8, which are paired and also facing each other respectively, and a solid laser medium is fixed in the center among them and further the refrigerant 10 and 11 are prepared in order to cool the amplifier. The exciting beam from respective LDs 1 and 2 is almost absorbed into the medium 9, however, remaining exciting beam is reflected on the plates 5 and 6 to pass through the medium two times, thereby the spatial distribution of gain can be equalized.
