    Abstract: A master oscillator power amplifier (MOPA) system includes an oscillator (12) having a neodymium-doped gadolinium vanadate gain- medium and delivering seed-pulses. A length of single mode fiber (14) is used to broaden the spectrum of the seed pulse. An amplifier (16) having a neodymium-doped yttrium vanadate gain-medium amplifies the spectrally broadened seed-pulses. The gain-spectrum of the amplifier partially overlaps the broadened pulse-spectrum, providing spectral selection of the seed-pulses in addition to amplification. This provides amplified output-pulses having a duration about one-third that of the corresponding seed-pulses.

These crystals contain dopants such as MgO or ZnO and/or have a specified degree of stoichiometry that ensures high reliability. The laser includes a solid- state gain media chip, such as Nd: YVO 4 , which also provides polarization control of the laser; and a periodically poled nonlinear crystal chip such as PPMgOLN or PPZnOLT for efficient frequency doubling of the fundamental infrared laser beam into the visible wavelength range. The described designs are especially advantageous for obtaining low- cost green and blue laser sources. Also described design of the continuously operated laser with an electro-optic element for modulation of the intensity of the laser output at frequencies up to hundred of megahertz. Such modulation is desired for various applications, including compact projectors with high resolution.

    Abstract: Anisotropic crystals such as Nd:YVO 4 , Nd:YLF, and Nd:GdVO 4 have become preferred gain materials for many laser applications. The anisotropic gain medium without ancillary compensation ensures there is no degradation of laser modes when passing through the gain medium. An optical power amplifier that incorporates an anisotropic gain medium achieves power scaling with multiple passes while also maintaining good mode matching between the laser and the pump during each pass. Preferred embodiments implement for multiple passes of a seed laser beam (100) through an anisotropic gain medium (102) with substantially zero angular beam displacement during each pass. The multi-pass system provides an economical, reliable method of achieving high TEM 00 power to meet the demands of micromachining, via drilling, and harmonic conversion applications.

    Abstract: A method for optically pumping a gain-medium with partially polarized or un-polarized pump-light having a wavelength at which that gain-medium has an absorption that is dependent on the polarization plane of the pump-light is disclosed. The pump-light is directed into the gain- medium. The strongest-absorbed polarization component of the pump- light is substantially absorbed and the weakest-absorbed polarization component is partially transmitted by the gain-medium. The polarization plane of the transmitted component is rotated through 90 degrees and the polarization-rotated pump-light is directed back into the gain-medium, wherein it is substantially absorbed.
