An optical coupler (30) is configured to combine the first optical pulse train with a second optical pulse train received from a reference source (28, 52) at a reference PRR. An optical detector (32) is coupled to output an electrical beat signal in response to constructive interference between the combined first and second optical pulse trains. Control circuitry (38) is configured to adjust the PRR of the laser responsively to the electrical beat signal.

摘要： A hybrid laser source including a solid state laser driven by an array of fiber laser amplifiers, the inputs of which are controllable in phase and polarization, to compensate for distortions that arise in the solid state laser, or to achieve desired output beam properties relating to direction or focus. The output beam is sampled and compared with a reference beam to obtain phase and polarization difference signals across the output beam cross section, at spatial positions corresponding with the positions of the fiber laser amplifiers providing input to the solid state laser. Therefore, phase and polarization properties of the output beam may be independently controlled by predistortion of these properties in the fiber laser amplifier inputs.

摘要： One embodiment is directed towards a stabilized laser (100) including a laser (312,902,1002) to produce light at a frequency and a resonator (106) coupled to the laser such that the light from the laser circulates therethrough. The laser also includes Pound-Drever-Hall (PDH) feedback electronics (204) configured to adjust the frequency of the light from the laser to reduce phase noise in response to light sensed at the reflection port of the resonator and transmission port feedback electronics (104) configured to adjust the frequency of the light from the laser toward resonance of the resonator at the transmission port in response to the light sensed at the transmission port of the resonator, wherein the transmission port feedback electronics adjust the frequency at a rate at least ten times slower than the PDH feedback electronics.

摘要： Embodiments herein provide for an optical frequency synthesizer including a coarse optical frequency comb (104), a fine optical frequency comb (102), and an output laser (26). The coarse comb is pumped with a first pump laser, and an absolute frequency of at least one tooth (112) of the coarse optical frequency comb is set. The fine comb is pumped with a second pump laser and has a frequency spacing between teeth that is locked to a fractional or integer multiple of a radio frequency reference. Initially, the second pump laser is locked to a first tooth of the coarse optical frequency comb. The optical frequency synthesizer can be tuned by sweeping the second pump laser and locking the second pump laser to a desired tooth. An output signal can then be generated with the output laser based on a tooth (16) of fine comb after the second pump is locked to the desired tooth.
