摘要： The present invention eliminates the halo ring of a solid state laser's output by creating a surface finish of the crystal element (20), which is matte only over part of its surface. The present invention also employs mirrored surfaces (124, 126) applied to the ends of the crystal element. By making the crystal and mirrors part of the same element, the invention eliminates the problems associated with misalignement of the element and the mirrors. Combining the mirrors and crystal in a single element permits nonrigid mounting of the crystal element. Thus, the present invention employs the crystal mirror element mounted by means of an elastomeric material (128, 130). The elastomeric material provides a self-centering action to properly position the element, so as to capture the light energy from the laser excitation source (22) while allowing for movement of the element due to thermal expansion.
摘要翻译：本发明通过产生晶体元件（20）的表面光洁度来消除固体激光器的输出的晕环，其仅在其表面的一部分上是无光泽的。本发明还采用施加到晶体元件的端部的镜面（124,126）。通过使晶体和镜子成为相同元件的一部分，本发明消除了与元件和反射镜的未对准相关的问题。将镜子和晶体组合在一个元件中可以允许非刚性地安装晶体元件。因此，本发明采用通过弹性体材料（128,130）安装的水晶镜元件。弹性体材料提供自对中动作以适当地定位元件，以便从激光激发源（22）捕获光能，同时允许元件由于热膨胀而移动。

摘要： The proposed method for generating laser radiation includes creation of an excitation flux for the active material of a hollow cylindrical element, continuous and uniform excitation of said material, providing for a plane-parallel electromagnetic field having in its cross-section the form of a ring generating an annular laser radiation at the frequencies of the induced radiation of the active material, and suppression of non-axial components of the laser radiation. At the same time in the resonating annular electromagnetic field the longitudinal modes are suppressed, excepting ''TEMoo'' modes at the frequencies of the induced radiation, by choosing the width of the resonating field ring equal to or exceeding the threefold geometric mean of the length of said field and by choosing the maximum wave length of the mode ''TEMoo'' from energetically significant modes ''TEMoo'' at the ratio of the internal diameter (D1) to the external diameter (D2) of said ring equal to or exceeding 0.09. In the proposed laser device the wall (9) of a hollow cylindrical element (2) of the active material of a resonator (7) has the thickness equal to or exceeding the threefold geometric mean of the optical length (L) of the resonator (7) and of the maximum wave length of the mode ''TEMoo" at the ratio of the internal diameter (D1) of the hollow element (2) to its external diameter (D2) equal to or exceeding 0.09. The source of the excitation flux consists of a continuous pumping flow-discharge lamp (8, 13) shaped as an annular hollow cylinder located coaxially to the cylindrical element (2).

The multi-purpose housing includes an interior filled with a material forming at least a light source and further comprising a reflector which can envelope a laser rod surrounded by light sources for providing light excitation to the laser rod. A material defining outer surfaces of the light sources extends out to and defines outer surfaces of the reflector. A high-reflectivity coating is disposed over an outer surface of the reflector, as is a protective coating. Also disposed over an outer surface of the reflector can be an optional heat sink, with cooling being performed by an optional arrangement of forced-air traveling over the heat sink. The light sources may be light source pumps, and the high-reflectivity coating may be formed to envelop the reflector.
