摘要: A variable pulse width lasing device for selectively reducing the amount of laser energy provided during a surgical procedure is described. The device includes a central processing unit, a laser resonator, pulse width detector and a pulse modulator. The central processing unit provides a switch activation command to the modulator. The modulator also receives a laser pulse produced by the laser resonator which has an initial pulse width and a wavelength which is compatible for transmission through an optical fiber. The modulator varies the width of the laser pulse for providing an output pulse at a selected pulse width and energy level.

摘要: A split-flow laser cooling assembly for providing separate cooling environments for the pumping medium and the laser medium. The device includes a generally transparent monoblock, a pumping medium for providing pump light, and a laser medium responsive to the pump light for generating laser energy. The monoblock is generally transparent and has a first open bore and a second open bore oriented with axis' parallel to each other. The first bore receives the pumping medium such that a pump cooling passage is provided between the monoblock and the pumping medium. Likewise, the second bore receives the laser medium such that a laser cooling passage is provided between the laser medium and the monoblock.

摘要: A MEMS-based optical, wireless communication system (10) that is comprised of a receiving and transmitting optical unit (12) that is further comprised of a transmitting subsystem (14) and a receiving subsystem (60), both of which are controlled by a microcontroller (16) and firmware (96). The system (10) is designed to allow a first unit (12) to transmit through free space a modulated laser beam (39) that is received by a second unit (12) located within line-of-sight of the first unit (12). Conversely, the second unit (12) can likewise transmit a modulated laser beam (39) that is received by the first unit (12) or other line-of-sight units (12). The system (10) features a MEMS mirror assembly (34) that operates in combination with a quad sensor (100). The combination allows fast, precise tracking and compensates for atmospheric disturbances associated with optical communication namely, building sway, wind and scintillations caused by changes in the refraction index of the atmosphere.
