    摘要： A laser system generates suitable laser power for use in photodynamic therapy, and particularly photodynamic therapy using dyes which undergo desired photodynamic reactions at 659 mm, i.e., Purpurin. The laser system generates a red output power of greater than 4 watts. For the therapeutic applications, a means for delivering the red beam to therapeutic sites is provided. The laser system provides for a frequency doubled solid-state laser system in which the non-linear birefringent crystal used to provide frequency doubling is mounted adjacent a flat mirror whereby losses due to walkoff of the beam caused by the crystal are minimized. The laser resonant cavity defined by one flat and one other mirror, which may be stabilized by means, such as thermal lensing in the solid-state gain medium, inside the cavity. A frequency doubled Nd:YAG rod in such cavity tuned to 1.319 microns with a KTP frequency doubling crystal for generates an output beam at 0.659 microns via type II phase matching required for photodynamic therapy in conjunction with a suitable PDT compound or dye.

    摘要： A method is disclosed for curing epoxy adhesive between the slider head and load/gimbal suspension assemblies of a disk drive access actuator employing a concentrated pulsed heat source rather than conventional, broadly applied heat source as employed in the past, such as oven heating or UV exposure. The laser source power is delivered via an optical fiber to the slider air-bearing surface (ABS) of the slider head assembly so that with this approach, the time for curing can be minimized and accurately controlled without causing damage to the assembly, and the overall curing step in the manufacturing process is reduced in time of application. Apparatus in the form of a fixture, such as an anvil element, provides a convenient gauge and support for alignment of the laser output beam with the slider ABS to which the heat for curing is to be applied as well as provide for its heat sinking.

    摘要： A multistage optical amplifier pumping system with built-in redundant reliability for lightwave communication system provides plural levels of redundancy. A first level of redundancy deals with redundancy in the form of plural primary laser diode sources for pumping a single fiber laser pump source. A second level of redundancy deals with redundancy of a plurality of fiber laser pump sources for pumping a plurality of serially connected injection signal fiber amplifiers forming the multistage amplifier system. If one of fiber pump sources should fail, increased pumping power is available from the remaining fiber pump sources via their respectively connected amplifier stages. A third level of redundancy deals with redundancy in the employment of multiple single mode laser emitters on the same chip or bar sufficiently segmented and/or electrical isolated so as not to interfere with operation of or cause failure to adjacent or neighboring emitters on the same chip or bar.

    摘要： A system and method for distributing an output beam from a laser system on a body which provides for a uniform fluence level throughout an entire treatment region. A first structure receives the laser beam and aims it along a propagation axis. A scanner scans the propagation axis of the laser beam at a controlled scan velocity, so that the laser beam essentially continuously scans a treatment pattern on the body. The treatment pattern can consist of an essentially straight line, or a ring, or other pattern which can be easily fitted together with other patterns to fill in a treatment area.The method includes the steps of:supplying a laser beam,directing a laser beam along a propagation axis to the body, andscanning the propagation axis of the laser beam at a controlled scanned velocity, so that the laser beam essentially continuously scans the treatment pattern on the body.
