摘要： Apparatus and a related method for generating a second harmonic frequency optical output from a fundamental frequency input beam, without significant birefringence. The apparatus includes two Type II doubler crystals of equal length arranged with their corresponding axes parallel to each other, and a polarization rotator positioned between the doubler crystals, to rotate the polarization angle of a residual fundamental frequency component of an output beam from one of the crystals by 90.degree. or an odd multiple of 90.degree.. Random birefringence introduced into one of the doubler crystals is virtually canceled in the other, and the assembly of the two crystals and the polarization rotator may be angularly adjusted as needed for phase matching or tuning, without detracting from the birefringence compensation capability. The invention is also disclosed in the context of a phase conjugated master oscillator power amplifier (PC MOPA) system.

摘要： A wavelength conversion apparatus using a nonlinear optical element for generating light different in wavelength from an incident fundamental wave. This apparatus utilizes a nonlinear optical element or a focusing lens element in the conversion apparatus to spatially separate light generated by the nonlinear optical element from the fundamental wave. For example, a cylindrical lens 13 for adjusting the size of the light beam is placed at least behind a wavelength conversion nonlinear optical crystal 12, and a light beam from the crystal 12 is passed through the lens near its edge, at a distance, from the central axis of the lens 13. The light beam is subject to a prism effect, and the generated beam B is separated from fundamental wave A as a result of the refractive index dispersion of the lens 13 and is transmitted.

摘要： A gain medium is disposed between two mirrors to form a resonant cavity. The cavity length is selected so that the gain bandwidth of the gain medium is less than or substantially equal to the frequency separation of the cavity modes and such that a cavity mode frequency falls within the gain bandwidth. A nonlinear optical material is disposed either inside or outside the cavity to generate new laser wavelengths. The nonlinear optical material may be contained in a cavity which is resonant at the microchip laser frequency. Alternatively, the microchip laser may be tuned, for example thermally or by the application of a longitudinal or transverse stress, to the frequency of the resonant cavity. The laser is optically pumped by any appropriate source such as a semiconductor injection laser or laser array. Suitable gain media include Nd:YAG, Nd:GSGG and Nd pentaphosphate, and suitable non-linear optical material include MgO:LiNbO.sub.3 and KTP.

摘要： A method and apparatus for second harmonic generation of laser light includes a non-linear birefringent crystalline element and a dynamic laser rod which has two transmission faces and an optical axis, the face of the dynamic laser rod facing the non-linear birefringent crystalline element being inclined at an angle to the optical axis of the dynamic laser rod so that the optical axis of the birefringent crystalline element forms a Brewster angle with a normal to the inclined face of the dynamic laser rod. Thus, the internal space occupied by the second harmonic generating apparatus is reduced and the supporting structure is miniaturized.

摘要： A tunable ytterbium-doped solid-state laser has a laser cavity defined a r of mirrors, a laser medium positioned in this cavity, means for pumping the laser medium, and means for tuning the output of this laser medium to a selected wavelength within a wavelength range. The laser medium has a host material doped with enough ytterbium ions to produce a longitudinal mode laser emission when the laser medium is pumped. In a most preferred embodiment, the laser emission is frequency-doubled and tuned to a wavelength corresponding to a Fraunhoffer line in the solar spectrum.
