    Abstract: Techniques and structure are disclosed for implementing a spatial walk-off compensation mechanism having an integral tilt function. In some embodiments, the mechanism may comprise a tilt-ball mount having an integrated walk-off compensation medium. In some embodiments, the mechanism may be configured to receive an output beam from a non-linear converter (e.g., optical parametric oscillator or OPO) implementing a non-linear medium comprising a bi-refringent material (e.g., zinc germanium phosphide, or ZnGeP2; cadmium silicon phosphide, or CdSiP2). In some embodiments, the walk-off compensation medium may comprise the same material and/or have the same cut as the non-linear medium. In some embodiments, the mechanism may be manually and/or mechanically adjusted/repositioned to reduce beam walk-off and/or to more precisely direct the beam. In some embodiments, the mechanism may be implemented in mid-infrared (MIR) applications. Numerous configurations and variations will be apparent in light of this disclosure.

    Abstract: A borosilicate glass composition comprises SiO2 having a concentration of about 40 mole percent to about 60 mole percent, B2O3 having a concentration of about 10 mole percent to about 30 mole percent, and an alkaline earth and/or alkali compound having a concentration of 10 mole percent to about 40 mole percent. An optical fiber amplification device comprises a borosilicate glass material cladding. The core comprises a germanate glass material doped with Tm3+. The germanate glass material has a first surface configured to receive an optical signal having a wavelength of from about 1400 nm to about 1540 nm and a second surface configured to output an amplified optical signal. In this manner, low cost fiber amplifiers in the 1450-1530 nm wavelength region (corresponding to the S-band) can be achieved.

    Abstract: A laser system in which the laser medium is a single crystal of Cr.sub.3+ :Mg.sub.2 SiO.sub.4 is disclosed. In one embodiment, the system comprises a single crystal of chromium doped forsterite and a cavity which includes a pair of 30 cm. radius mirror having high transmission at 543 nm (the pump wavelength) and high reflectivity in the 1150-1350 nm range. Room temperature vibronic pulsed laser action is obtained with this cavity. Laser action has been observed at 1235 nm and a bandwidth of 25 nm. The wavelength range is suitable for transmission through optical fibers and is useful in laser ranging and remote sensing. Because of the ultrawide fluorescence bandwidth and a 15 fluoroescence lifetime the system is suitable for high intensity, tunable, cw, Q switched mode locked operation. In the mode locked operation pulses as short as 10-500 femtosecond may be generated. A number of different embodiments of the invention are described.
