摘要： Apparatus for marking a bitmap image on tape includes a source of a modulatable laser-beam. The beam is directed to an oscillating mirror on a carriage translatable across the width direction of the tape. The oscillating mirror directs the beam to a focusing lens mounted on the carriage. The focusing lens is arranged to focus the beam to a focal-spot on the tape. As the carriage is translated, the focal-spot is swept reciprocally in a wave-like path across the tape. Modulation of the beam is arranged such that pixels of a plurality of rows of the bitmap image are printed in one traverse of the carriage. The tape is advanced incrementally and repeated traverses of the carriage are made to complete printing of the bitmap image.

摘要： In laser engraving apparatus for engraving a gray-scale image on a plastic ID-card, the laser is a modulatable optically pumped semiconductor laser. Focusing optics focus a beam from the laser into a focal spot about 10 micrometers in diameter. The ID-card is mounted on a turntable which is rotated such that the focal spot sweeps over the ID card. The turntable is translated in a direction transverse to the rotation direction and the laser is modulated such that the engraved gray-scale image is formed by a matrix of parallel black lines of various length and spacing.

摘要： A focused laser beam having an optical axis passes through a first lens mounted to a first galvanometer and a second lens mounted to a second galvanometer. The first galvanometer is adapted to tilt the first lens about a X axis and the second galvanometer is adapted to tilt the second lens about a Y axis. This displaces the focused laser beam in a controlled manner from the optical axis to enable laser machining of very precise geometric features over a large processing window. In a preferred embodiment, the first and second lenses are a pair of inverted positive meniscus lenses, of high index of refraction material.

摘要： Laser systems have a line-narrowed master oscillator and a power oscillator for amplifying the output of the master oscillator. The power oscillator includes optical arrangements for limiting the bandwidth of radiation that can be amplified. The limited amplification bandwidth of the power oscillator is relatively broad compared to that of the output of the master oscillator, but narrower than would be the case without the bandwidth limiting arrangements. The bandwidth narrowing arrangements of the power oscillator function primarily to restrict the bandwidth of amplified spontaneous emission generated by the power oscillator.

摘要： A projection display including a one-dimensional light modulator includes an optical arrangement for projecting light from a laser onto the modulator in the form of a line of light. Light from the laser is divided to create in effect a two-dimensional array of mutually incoherent light sources. Light from one axis of the array is projected onto the modulator to form the length of the line of light and light from the other axis of the array is projected onto the modulator to form the width of the line of light. Division of the light is accomplished without the use of any moving component.

摘要： A frequency-doubled, edge-emitting semiconductor laser includes a separate confinement heterostructure surmounted by a waveguide including a converting layer of a periodically poled, optically nonlinear material. Fundamental radiation generated in the heterostructure is directionally coupled from the heterostructure into the waveguide, is converted to second-harmonic radiation in the converting layer and is delivered from the waveguide as output radiation. In one example, a distributed Bragg grating is included at an interface between the heterostructure and the waveguide for facilitating coupling of fundamental radiation from the heterostructure into the waveguide.

摘要： A wavelength-locking arrangement for a diode-laser bar includes a cylindrical fast-axis collimating lens and a fast-axis corner reflector. An optical filter is located between the cylindrical lens and the corner reflector for defining the locked wavelength. The corner reflector provides that radiation emitted by each of the diode-lasers and collimated by the cylindrical lens is reflected back to the cylindrical lens and is focused by the cylindrical lens back into the diode-laser from which the radiation was emitted, independent of the fast-axis alignment of the diode-laser with the cylindrical lens.
