    摘要: A method and apparatus for performing optical coherence tomography using a wavelength multiplexed source is provided. The single output beam of the source is of a large bandwidth, thus providing a high resolution tomography system. In order to achieve high contrast as well, the wavelength multiplexed source has minimal wavelength separation between spectrally adjacent lasers and has an output beam with an approximately Gaussian spectral shape. The source is preferably comprised of one or more multi-gain element arrays multiplexed together within a single external resonator cavity. Interposed between the array and the resonator cavity output coupler are a collimating element and a diffraction grating. The collimating element can be a refractive optic, a reflective optic, or, for some applications, a ¼ pitch GRIN lens. The diffraction grating can either be transmissive or reflective. The combination of the diffraction grating and the collimating element forces each emitter within the array to lase at a distinct wavelength. In order to achieve an overall bandwidth greater than the gain bandwidth of a single emitter array, either multiple arrays of differing center wavelength are packaged together or a large array is used with a laterally varying quantum well thickness or epitaxy. An intracavity spatial filter can be used to improve the beam quality and reduce cross-talk. An optical coherence tomography imaging system is coupled to the resonator cavity.

    摘要: A wide variety of Fiber Bragg writing devices comprising solid state lasers are provided. The solid state lasers emit moderate peak-power output beams which are suitable for efficient production of fiber Bragg gratings without causing embrittlement of the optical waveguide. These solid state lasers generate fourth harmonic output beams with wavelengths of approximately 240 nm, in order to match the primary absorption peak in the ultraviolet range for a typical optical waveguide. Some of these solid state lasers comprise a fequency-doubling crystal and a CLBO crystal used in a non-critically phase-matched orientation as a frequency-quadrupling crystal. In such lasers, both the frequency-doubling crystal and frequency-quadrupling crystal are preferably engineered to minimize or eliminate beam “walkoff.”

    摘要: A method and apparatus for obtaining multiple wavelengths of varying temporal format from a single solid state laser are provided. Accordingly, the output from the solid state laser can either be sent through a series of non-linear crystals to obtain UV radiation or through an OPO cavity to obtain IR radiation. In order to provide the different wavelengths in the temporal formats commonly used for various medical procedures, the laser source may be operated in two different modes. When the laser system produces UV radiation a pulse of short duration is desired and the laser source is operated in the standard Q-switched mode or is mode locked. Conversely, when the laser system produces IR radiation, a pulse of long duration is desired and the laser source is operated in the free running mode. The outputs from the UV and IR portions of the system can either be directed to the object to be treated through a common beam delivery system or through separate beam delivery systems, for example utilizing optical fibers or waveguides.

    摘要: A solid state laser system producing coherent radiations at deep ultraviolet wavelengths includes a solid state laser producing a first beam having a wavelength near 1 micron. The 1 micron beam is passed to both a harmonic generation stage and to a tunable optical parametric oscillator. The harmonic generation stage is configured to produce a fifth harmonic of the 1 micron beam, while the optical parametric oscillator produces a tunable beam in the near infrared spectrum (e.g., approximately 2.075 micron). The fifth harmonic and the near infrared beams are mixed in a sum frequency generator to produce a highly coherent beam in the deep ultraviolet (e.g., between approximately 180 nm to 213 nm).

These solid state lasers generate output beams with wavelengths of approximately 240 nm, in order to match the primary absorption peak in the ultraviolet range for a typical optical waveguide. Some of these solid state lasers generate tunable wavelength beams using an optical parametric oscillator (“OPO”), then generate harmonics of these tunable beams. Other lasers mix the tunable beam with fixed wavelengths derived from the pump laser to reach the desired output wavelength.

    摘要: A diode pumped slab laser (DPSL) that is cooled by a capillary heat pipe cooling apparatus. The DPSL contains a diode array that is cooled by one or more capillary evaporators that are adjacent to the diode array of the DPSL or contained within a thermally conductive substrate surrounding the diode array of the DPSL. The capillary evaporators convert the liquid phase of a working fluid to a vapor phase which is circulated to a condenser. The condenser causes the phase of the working fluid to change to a liquid phase which is then drawn back to the capillary evaporators by the evaporation of the working fluid within the capillary evaporator. In one embodiment, the diode array is interleaved with heat sink strips that conduct the heat away from the diode array strips and toward a closely spaced capillary evaporator wick facing the diode array. The vapor is carried away from the diode array in the channels formed between consecutive heat sink strips.
