    摘要: A laser amplifier includes a laser active slab with a source of pump power to amplify an input laser beam, the laser active slab including a block of laser active material having opposed lateral faces defining a wedge lateral dihedral angle specified to minimize parasitic amplified spontaneous emission. The laser amplifier may include one or more external mirrors highly reflecting at the lasing wavelength positioned and oriented to provide for zig-zag passes through the gain sheet for the input laser beam to yield a multi-pass-amplified laser beam. The source of pump power may be one or more laser diode bars and microlenses producing a gain sheet in the laser active slab.

    摘要: A laser system according to the invention comprises pump generating means (x02, x03) for generating at least a first and a second, preferably focused, pump beam, and lasing means (x06, x07) for emitting radiation by being appropriately pumped. The lasing means (x06, x07) is disposed in a first resonator so as to receive the first pump beam in order to generate a first beam (x21) having a first frequency, and the lasing means (x06, x07) is disposed in a second resonator so as to receive the second pump beam in order to generate a second beam (x22) having a second frequency. At least one Q-switch (x08; x17, x18) is disposed in the first and the second resonator, so that the first beam and the second beam both pass a Q-switch (x08; x17, x18). The laser system (x01) has an output (x13) generated from said first beam (x21) and said second beam (x22), and at least a part of said output (x13) is fed back to a regulation system (x14), said regulation system (x14) controlling said pump generating means (x02, x03).

    摘要: An electroluminescent material slot waveguide generates light in response to current injection. In one embodiment, the waveguide is formed as part of an optical resonator, such as ring resonator waveguide or distributed Bragg reflector with an anode and cathode for electrical stimulation. A compact, electrically-driven resonant cavity light emitting devices (RCLED) for Si microphotonics may be formed. Several different rare-earth ions, such as erbium, terbium and ytterbium, can be used to dope SiO2 in order to emit light at different wavelengths.

    摘要: A photonic device is disclosed which has higher order harmonic emissions. A pump source is adapted to emit a laser beam at a source frequency and to have a power output of less than approximately 100 Watts. A micro-cavity resonator, which is adapted to exhibit inversion symmetry, is optically coupled to the pump source to receive light from the laser beam. The micro-cavity resonator emits light at an emission frequency while light is received from the laser beam, where the emission frequency is approximately three or more times the source frequency.

    摘要: The present invention relates to a rotationally asymmetric chaotic optical multi-pass cavity useful in optical gas sensing spectroscopy, optical delay lines, and laser amplification systems, for example. The cavity may include a single closed mirror having a light reflective surface that is deformed in two orthogonal directions and more particularly, but not exclusively, in the shape of a quadrupole in both horizontal and vertical planes. The cavity includes a light entry port and a light exit port which may be the same or separate ports, as well as a gas inlet and a gas outlet. The optical path length, the beam divergence rate, and the spot pattern are controlled by selecting the cavity deformation coefficients and the input beam direction to achieve the desired beam path and beam quality.
