摘要： A laser includes a narrow bandwidth AR coating for defining a frequency range for laser emission within the laser cavity. Advantageously, the narrow-band AR coating has a very low loss, which can be particularly useful if the gain medium has low gain. The narrow-band AR coating can be used to narrow the laser emission from a broadband gain medium (e.g. Cr:LiSAF), or to select from among discrete transition lines (e.g. Nd:YAG) without the use of cumbersome tuning elements. An etalon may be utilized to further narrow the fundamental wavelength, and the etalon may be substantially uncoated. For a solid state gain medium, the AR coating may be formed on one of the optical faces. A nonlinear element may be included for frequency-conversion, and the AR coating constrains the lasing frequency in the presence of this nonlinear loss and assists in maintaining single frequency operation to provide a stable frequency-converted output.
摘要翻译：激光器包括用于定义激光腔内的激光发射的频率范围的窄带宽AR涂层。有利地，窄带AR涂层具有非常低的损耗，如果增益介质具有低增益，则其可以是特别有用的。可以使用窄带AR涂层来缩小来自宽带增益介质（例如Cr：LiSAF）的激光发射，或者不使用繁琐的调谐元件从离散过渡线（例如Nd：YAG）中进行选择。可以使用标准具进一步缩小基本波长，并且标准具可以基本上未涂覆。对于固态增益介质，可以在其中一个光学面上形成AR涂层。可以包括用于频率转换的非线性元件，并且AR涂层在存在这种非线性损耗的情况下约束激光频率，并且有助于维持单频操作以提供稳定的频率转换输出。

摘要： A moving solid state laser gain structure is optically pumped by optical pumping radiation derived from a remote bank of diodes, preferably laser diodes. The pumping radiation is guided and concentrated from the bank to the laser gain structure over a bundle of fiber optic waveguides. In some embodiments, the laser gain structure is a slab of Nd:Glass or Nd:YAG. In some embodiments, the lasant beam is internally reflected within the slab over a zig-zag path. In one embodiment, the lasant slab is a rotating and translating disk with the pumping radiation being applied collinearly of the beam of lasant radiation. In another embodiment, the lasant slab is made up of a bundle of fiber optic waveguides.

摘要： Apparatus and methods for producing ultrashort optical pulses are described. A high-power, solid-state, passively mode-locked laser can be manufactured in a compact module that can be incorporated into a portable instrument. The mode-locked laser can produce sub-50-ps optical pulses at a repetition rates between 200 MHz and 50 MHz, rates suitable for massively parallel data-acquisition. The optical pulses can be used to generate a reference clock signal for synchronizing data-acquisition and signal-processing electronics of the portable instrument.

摘要： Provided is a solid-state laser device in which a linear resonator including an output mirror and a rear mirror, a laser rod, and optical members are provided on a common base and are contained in a housing having the base as a portion. A holding part is provided to hold an excitation light source that extends parallel to the laser rod on a side of the laser rod opposite to the base. The optical members including a Q-switch are disposed between the laser rod and the rear mirror. An upper end position of the output mirror is at a position lower than a lower end position of the excitation light source held by the holding part, with the base as a reference. The holding part holds the excitation light source so as to be capable of being inserted and extracted with respect to the output mirror side in a longitudinal direction of the excitation light source.
