    摘要： A high power source of electro-magnetic radiation having a multi-purpose housing is disclosed. 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.

    摘要： A laser system and method. The inventive laser includes an annular gain medium; a source of pump energy; and an arrangement for concentrating energy from the source on the gain medium. In a more specific implementation, a mechanism is included for rotating the gain medium to effect extraction of pump energy and cooling. In the illustrative embodiment, the pump source is a diode array. Energy from the array is coupled to the medium via an array of optical fibers. The outputs of the fibers are input to a concentrator that directs the pump energy onto a pump region of the medium. In the best mode, plural disks of gain media are arranged in an offset manner to provide a single resonator architecture. First and second mirrors are added to complete the resonator. In accordance with the inventive teachings, a method for pumping and cooling a laser is taught. In the illustrative embodiment, the inventive method includes the steps of providing a gain medium; pumping energy into a region of the gain medium; moving the medium; extracting energy from the region of the medium; and cooling region of the medium.

    摘要： In order to avoid problems associated with thermal distortion, loss of energy, and destruction of system components, the invention provides a means for producing, for the first time, high repetition rate, high power pulses while avoiding thermal distortion and its attendant difficulties. The invention provides the ability to remove heat generated from the gain media (lasant material) and to repeatedly extract energy from the media without the accumulation of heat in the media which causes thermal distortions. The invention avoids thermal distortions by pumping an unheated gain region every time an optical pulse is incident thereon. In one aspect, the gain media is essentially uniformly pumped using an essentially instantaneous uniform spatial profile provided by a multi-mode oscillator. The resulting instantaneous uniform temperature profile does not create thermal gradients, thus, no thermal distortions occur. In the invention, the total time duration of pumping and lasing or amplification takes place while the thermal profile remains uniform in the region of the media in the beam path. Thus, no thermal distortions occur during the time of pumping and lasing or amplification. Heat is preferably extracted at about the same rate it is generated in the lasant material (media).

    摘要翻译： 为了避免与热失真，能量损失和系统部件的破坏相关的问题，本发明提供了一种首次制造高重复率，高功率脉冲同时避免热变形及其伴随的困难的手段。 本发明提供了去除从增益介质（惰性材料）产生的热量并且能够重复地从介质中提取能量的能力，而不会在导致热失真的介质中积聚热量。 本发明通过在每次光脉冲入射时泵浦未加热的增益区域来避免热失真。 在一个方面，使用由多模式振荡器提供的基本上瞬时均匀的空间分布，增益介质基本均匀地泵送。 所产生的瞬时均匀温度分布不会产生热梯度，因此不会发生热变形。 在本发明中，泵送和激光或放大的总持续时间发生在热分布在光束路径中的介质区域中保持均匀的情况下。 因此，在泵浦和激光或放大期间不会发生热失真。 优选以大致相同的速率提取热量，其在惰性材料（介质）中产生。

    摘要： A laser apparatus includes a hollow cylindrical solid state laser medium and an optical resonator having reflective surfaces at each end of the laser medium in the axial direction of the laser medium for causing a light emitted into the laser medium to travel back and forth along the elongated axial direction of the laser medium. One of the reflective surfaces of the optical resonator is shaped to reflect the beam at an angle to the beam impinging thereagainst to thereby walk the beam tangentially around the hollow cylindrical solid state laser medium at a fixed radial distance from the elongated axis of the laser medium. An exit slot is formed in one of the reflective surfaces. A pumping means for exciting the laser medium includes at least one flashlamp positioned adjacent the laser medium along the laser medium axis through the hollow cylindrical portion of the laser.
