摘要： A solid-state laser in which a rod (10) of lasing material is held within an optical cavity formed within a cooling block (40) having a highly surface facing the rod. A longitudinal slit (44) formed in the block from the optical cavity to the outside allows the pumping light from an emission line (36) of semiconductor stripe lasers (30) fabricated on a laser bar (28) to irradiate the laser rod and multiply reflect within the optical cavity. Thereby, pump light is efficiently absorbed by the laser rod, and the laser rod is thermally controlled. Alternatively, cooling liquid (124) can flow axially along the laser rod and within an axially extending optical cavity formed by a reflective coating (125) deposited on a tube (122) enclosing the cooling liquid and having a slit (126) through which pump light is irradiated.

摘要： A system employing a solid state light source for writing Bragg gratings in fibers and for other photolithographic applications. The solid state light source preferably has a passively Q-switched laser, a fiber amplifier and two or more nonlinear conversion elements for delivering a pulsed exposure beam at an exposure wavelength in the UV wavelength range.

摘要： A source that employs an Erbium-Doped Fiber Amplifier (EDFA) for generating light in an S-band of wavelengths. The EDFA uses a fiber having a core with a core cross section surrounded by a depressed cladding with a depressed cladding cross section and a secondary cladding with a secondary cladding cross section. A pump source is provided for pumping the Erbium contained in the core of the fiber to a high relative inversion D, such that the Erbium exhibits positive gains in the S-band and high gains in a long wavelength band longer than the S-band. The core cross-section, the depressed cladding cross-section, and the refractive indices no, n1, and n2 are selected to produce losses at least comparable to the high gains in the long wavelength band and losses substantially smaller than the positive gains in the S-band. The source uses the amplified spontaneous emission (ASE) produced by the EDFA to generate broadband light and/or narrowband light with the aid of a wavelength selecting mechanism that selects an output wavelength of the light within the ASE emission spectrum of the EDFA.

摘要： A system and method for using pulses of laser light delivered in a non-overlapping sequence of first pulses at a green wavelength, second pulses at a blue wavelength and semi-continuous pulses at a red wavelength to illuminate a color generation unit for generating a color. Typically, the color generating unit is an image generating unit for producing color images and is equipped with transmissive or reflective pixels which are adjusted to select portions of the laser light generated at the green, blue and red wavelengths to obtain a desired output color. The first and second pulses preferably have a narrow pulse width and an interpulse separation equal to at least 100 times the narrow pulse width, while the semi-continuous pulses at the red wavelength have a wide pulse width equal to at least 100 times the narrow pulse width.

摘要： An optical resonator has an axial mode frequency tuning rate with respect to temperature matching the peak gain frequency tuning rate, so that mode hops are eliminated. The resonator contains a composite cavity consisting of a gain medium and free space. Preferably, the resonator is a single-frequency solid state laser containing a solid state gain medium defining a physical path length Lg. The optical cavity is defined by a high reflector and output coupler surrounding the gain medium and defining a physical cavity path length Lo. The high reflector and output coupler are mounted on a substrate so that Lo is temperature insensitive. Preferably, the substrate is a thermally insensitive material having a negligible coefficient of thermal expansion; for example, it may be Invar™, Super-Invar™, ULE™ Glass, Zerodur™, and fused silica. Alternately, the substrate is a thermally isolated material that is temperature controlled and insulated from the gain medium. When Lo=Lg, the axial mode tuning rate has a greater magnitude than the peak gain tuning rate. However, Lo/Lg is fixed and designed so that the axial mode tuning rate is identical to the peak gain tuning rate. In particular, L o L g = 1 - n g - ν m [ ( n g - 1 ) 1 L g ⅆ L g ⅆ T + ⅆ n g ⅆ T ⅆ ν g ⅆ T ] . The laser preferably contains means for ensuring single-frequency operation. For a ring laser, it may include a magnet and half-wave plate inside the cavity, coupled with rod-shaped gain material with anti-parallel Brewster facets. For a non-planar ring oscillator, the purpose of the half-wave plate is instead served by the non-planar path. Alternately, the resonator is an optical parametric oscillator.

摘要： A solid-state laser having a rod of active material optically pumped along the side of the rod by an array of diode lasers. Beam shaping elements, such as Brewster angle facets on the end of the laser rod, cause the laser beam to assume a generally elliptical shape within the rod with the long axis of the ellipse aligned with the irradiation angle of the diode lasers. However, the beam is circularly shaped outside the rod. Preferably, the laser rod is held within an optical cavity formed within a cooling block which both cools the rod and reflects pump light back into the rod. The diode lasers irradiate the rod through a linear slit in the cooling block. Also, preferably, a slab-shaped optical waveguide is placed within the slit to guide the light from the diode lasers to the side of the laser rod.
