摘要： A two-dimensional photonic crystal plane emission laser of the invention includes a two-dimensional photonic crystal which has a two-dimensional photonic crystal area and a light reflecting area, and which selects a wavelength of light to be generated in an active layer. The light reflecting area is formed in such a manner that when light leaking from the two-dimensional photonic crystal area and reflected on a reflecting surface of the light reflecting area is returned to the two-dimensional photonic crystal area, the reflection light is combined with a standing wave residing in a propagating direction of the reflection light without disturbing its resonant state.

摘要： A lasing method including the steps of providing a laser resonator; utilizing birefringence compensation in said resonator whereby said resonator is induced to operate in a Laguerre-Gaussian higher order mode; and utilizing polarized outcoupling of lasing energy at said higher order mode from said resonator. In the illustrative application, the laser resonator is a high-power, solid-state laser resonator. In the specific embodiment, the inventive method further includes the step of changing an outcoupling preference for a non-degenerate high-order Laguerre-Gaussian mode. In one embodiment, the step of changing outcoupling preference includes the step of changing an outcoupling polarization. In another embodiment, the step of changing outcoupling preference includes the step of changing an orientation of a roof edge of a prism in the laser resonator. Lower order Laguerre modes are discouraged from appearing in an output of the resonator by adding loss at the center of the rod aperture of the resonator or detuning the orientation of a first or a second quarter-wave plate. In the illustrative embodiment, the gain lifetime of the resonator is longer than an interpulse period thereof.

摘要： An optical resonator supporting two sets of simultaneously co-existent oscillation modes (30 and 31), having polarizations orthogonal to each other. Mode control elements (28 and 29), such as apertures and phase elements, are introduced into the resonator to allow only preferred modes to exist. The placement and orientation of the sets are designed such that the high intensity zones of one set fall on the nodes or low intensity zones of the other set in an interlaced pattern. Thus, in a laser resonator, better utilization of the gain medium (24) is achieved and the beam quality and brightness over multimode lasing are improved. This configuration improves the performance of high Fresnel number resonators, in both pulsed and continuous lasers, for applications such as scribing, drilling, cutting, target designation and rangefinding. An application of the intra-cavity coherent summation of orthogonally polarized modes is described, whereby azimuthally or radially polarized beams may be obtained.

摘要： In order to obtain a high-power laser beam with a high beam quality with use of a small-sized and low-cost apparatus, there has been disclosed a laser resonator which is constructed so as to produce a single high-order transverse mode laser beam, and a technique for converting the laser beam with a single high-order transverse mode into a laser beam with a high beam quality. The laser resonator is provided with a regulating plate of a high-order transverse mode which is constructed so as to produce a laser beam in a single high-order transverse mode. A phase adjusting plate inverts a phase for each region of the laser beam divided depending upon a lateral mode thereof to match the phase for each region of the laser beam, and subsequently, a traveling direction of the laser beam is changed for each position thereof by means of the first binary optics element, and further, the laser beam is converted into a parallel beam by means of the second binary optical element. The first binary optics element changes the traveling direction of the ray of the laser beam for each region thereof so that the laser beam has a desired intensity distribution on the second binary optics element.
