    摘要: Techniques, methods, systems, apparatus, and articles of manufacture that can be used for optical amplification may be particularly, though not exclusively, applicable to optical amplification using thin single crystal rods (TSCRs). Such TSCRs may be particularly useful for use in Master Oscillator - Power Amplifier systems. Use of TSCRs in such systems presents an attractive alternative to using glass fibers for ultra-short pulsing lasers with output power levels exceeding 100 W. Such systems are desirable because virtually any engineering material can be processed by ultra-short pulses and the achieved processing quality using such systems generally meets stringent quality requirements.

    摘要: A modular solid-state laser (10) comprises a fiber coupled diode-laser pump module (20) and a laser-enclosure (50). The diode-laser pump module comprises a connector assembly 26 including a collimating lens (32) and produces a collimated beam (28B) of laser-radiation for pumping a gain-element (56) within the laser-enclosure. The beam of pump laser-radiation is focused into the gain-element by optics (54) located within the laser-enclosure. The diode-laser pump module can be replaced or exchanged without realigning optics located within the laser-enclosure by detaching and replacing the connector assembly from the laser enclosure.

    摘要: The present disclosure relates to methods and apparatuses for providing optical radiation having improved rise/fall times and improved levels of leakage. One method for amplifying optical radiation includes an intermediate stage (220) having an intermediate active optical fiber (222), the intermediate active optical fiber and a final amplifying stage (230) including a final active optical fiber (232), and providing optical radiation to the input of the intermediate active optical fiber, wherein one or more final optical pump sources (235) are together in a low power state such that the optical radiation is substantially absorbed by the intermediate active optical fiber and such that substantially no optical radiation of the amplified wavelength is transmitted by the intermediate stage. The intermediate active optical fiber (222) can then be switched to a transmissive state by switching the final optical pump source(s) (235) to a high power state. The input to the intermediate stage may comprise a seed laser (205) and plural first amplifier stages (210) having each a first active optical fiber (212). A filter (260) between the intermediate stage (220) and the final amplifying stage (230) prevents ASE and pump light from the intermediate stage to reach the final amplifying stage.
