摘要： A slab laser amplifier with parasitic oscillation suppression has a plurality of angled pump faces related to one another in order to decrease likelihood of parasitic oscillations, with internal beam incidence angles at total internal reflection that alleviate need for reflective coatings. No polished surfaces of gain material comprising the amplifier are parallel to one another. A beam path within the gain material is such that all incident angles of the beam path upon the two main faces and the common end face are greater than a critical angle required for total internal reflection, thereby alleviating need for reflective coatings. Based on an index of refraction of the gain material, and based on a diameter of the laser beam, dimensions of the gain material are selected to maximize beam overlap in a pumped volume of the gain material.

摘要： An apparatus and method for making a grayscale photo mask and a three-dimensional grayscale diffractive optical element operate as follows. A grayscale photo mask is obtained by exposing a laser direct write (LDW) glass material to laser beam radiation from a first laser beam of modulated power moved over a grid of discrete locations on the LDW material, the modulated power being in accordance with grayscale pattern data, and, while the first laser beam is moved over the discrete locations of the grid, exposing the grid to a second laser beam, the power of the second laser beam being less than the bleach threshold of the glass material, to provide each of the discrete locations with a gray scale level to provide a predetermined gray scale pattern of varying optical transmissivity on the LDW material to produce a grayscale mask. An optical element is obtained by exposing a photoresist layer on a wafer to radiation transmitted through the grayscale mask; and removing material from the photoresist layer to provide a predetermined varying thickness of the photoresist layer as determined by the gray scale patterns on the grayscale mask to produce the three-dimensional grayscale diffractive optical element. The optical element may be a diffraction grating. The power of the second laser exposed on said discrete locations may be between about 50 mW and about 5 W, and the power of the first laser exposed on the discrete locations may be between about 20 mW and about 500 mW.

摘要： A positive photo resist is provided on a surface of a photo mask blank. Light is then exposed onto the photo resist to form a predetermined pattern of unexposed and exposed portions in the photo-resist. After development, the exposed portions are removed and ions are implanted to obtain a modulated ion density in the photo mask blank. The implanted ions become color centers which absorb a specific wavelength of light and the modulated distribution of the color substrates create the grayscale photo mask. The photo resist structure is finally removed to produce a grayscale photo mask.

摘要： An ultrafast laser machining system and method to form diffractive structures in optical fibers. The fiber is mounted with its longitudinal axis perpendicular to the beam path of the laser pulses. A region of the fiber is illuminated and then imaged with two cameras. These cameras are aligned substantially orthogonally. A position of the beam spot is determined. The beam spot is aligned to a starting position within the region. This position is within a portion of the fiber to be machined for which the beam path passes through the greatest length of material. The beam spot is scanned along a path designed to pass the beam spot through all of the portion to be machined such that the beam path does not pass through previously machined material. The laser pulses, which have a duration of less than about ins, are generated as the beam spot is scanned.

摘要： A method of operating a laser drilling system to manufacture gravure printing plates without etching or the use of hazardous chemicals includes activating a laser drilling system, including a picosecond laser, light valves, and a mechanism adapted to rotate a gravure cylinder blank. Operation of the light valves, includes setting the light valves to block and/or allow pulses of laser energy propagating from the laser drilling system that can ablate a linear pattern of cells along a substantially entire length of the gravure cylinder blank. Drilling of cells includes targeting the laser drilling system on the gravure cylinder blank, such that ablation of materials occurs as sub-beams propagate along an optical path to the target area and impinge upon the gravure cylinder blank, wherein specific cells within the target area of the gravure cylinder blank are drilled or not drilled according to settings of the light valves.
