    摘要: A Q-switched all-fiber laser utilizes a long period fiber grating (LPFG) modulator. The LPFG modulator is characterized by optical spectral characteristics that are controlled by application of stress via an actuator. In particular, the actuator applies stress to selected sections of the LPFG in order to modulate a light signal at a specified wavelength. Further, a controller is utilized to control the application of stress in the time domain, and thereby switch the Q-factor of the fiber laser cavity. In addition to the LPFG, the laser cavity comprises a pair of fiber Bragg gratings (FBGs) and a fiber gain medium.

    摘要: Described herein are methods, systems, and apparatuses to utilize a laser device comprising a gain section, a wavelength filter, a first reflector, and a second reflector to form a laser cavity with the first reflector, the laser cavity to include the gain section and the wavelength filter. The wavelength filter is temperature stabilized to a predetermined temperature range and the remaining portions of the laser cavity are not temperature stabilized. The wavelength filter, when at the predetermined temperature range, comprises a plurality of adjacent longitudinal modes such that a difference in modal gain values associated with each of the adjacent longitudinal modes is within a predetermined delta. Thus, the cavity of the laser device is designed to experience some mode hops when the device temperature changes; however, because the wavelength filter is stabilized in temperature, the cavity drift due to these mode hops is within a limited range.
