摘要： An electronic circuit for controlling a laser system consisting of a pulse source and high power fiber amplifier is disclosed. The circuit is used to control the gain of the high power fiber amplifier system so that the amplified output pulses have predetermined pulse energy as the pulse width and repetition rate of the oscillator are varied. This includes keeping the pulse energy constant when the pulse train is turned on. The circuitry is also used to control the temperature of the high power fiber amplifier pump diode such that the wavelength of the pump diode is held at the optimum absorption wavelength of the fiber amplifier as the diode current is varied. The circuitry also provides a means of protecting the high power fiber amplifier from damage due to a loss of signal from the pulse source or from a pulse-source signal of insufficient injection energy.

摘要： A pulsed laser comprises an oscillator and amplifier. An attenuator and/or pre-compressor may be disposed between the oscillator and amplifier to improve performance and possibly the quality of pulses output from the laser. Such pre-compression may be implemented with spectral filters and/or dispersive elements between the oscillator and amplifier. The pulsed laser may have a modular design comprising modular devices that may have Telcordia-graded quality and reliability. Fiber pigtails extending from the device modules can be spliced together to form laser system. In one embodiment, a laser system operating at approximately 1050 nm comprises an oscillator having a spectral bandwidth of approximately 19 nm. This oscillator signal can be manipulated to generate a pulse having a width below approximately 90 fs.

摘要： A nerve-stimulation device and method using light to provide a source of precise stimulation on one or more nerve fibers. In some embodiments, this simulation is provided through a device and method wherein a laser- or LED-light-generating source is operatively coupled to an optical fiber, which in turn is coupled to a plug in the end of a holder in a sheath. Light is then passed from the light source through the optical fiber to the holder and out a selected optical tip on the sheath to provide an efficacious amount of light to simulate nerves. In some embodiments, the device is constructed from non-magnetic material such as glass, plastic or ceramics. In some embodiments, the light emanating from the optical tip can be controlled manually or automatically. Some embodiments omit the fiber and use light directly from the laser diode.

摘要： An integrated-optic sensor includes a waveguide made from a substrate that is doped with rare-earth elements. A beam of light propagating along the waveguide excites these elements, causing them to emit light and thereby increase the total amount of light being propagated in the waveguide. The waveguide itself functions as a laser, so that any change in an optical property of an analyte material which forms a portion of the laser cavity can affect the operation of the laser. Consequently, the wavelength or power of light produced by the laser changes, in direct response to changes in the concentration of a material being sensed, and these changes are enhanced due to the inherent gain characteristics of the laser media.
