Compact laser source with frequency modulators generating multiple lines
| DWPI Title: Laser source, has seed laser adapted to generate laser beam, beam splitter adapted to receive laser beam and to split laser beam into many sub-beams; and at least one channel, each channel including frequency shifter adapted to receive respective one of many sub-beams,and to shift frequency |
| Abstract: A compact laser source and a single sideband modulator used therein is disclosed. The compact laser source includes a seed laser and one or more channels, with each channel generating one or more output laser beams having corresponding different wavelengths. The compact laser source can be formed in whole or in part on a single optical motherboard to thereby minimize space and power requirements. By employing the disclosed single sideband modulator, harmonics in the generated output laser beams can be minimized. The compact laser source finds application in an atom interferometer (AI) system, which may be used to measure gravity, acceleration, or rotation of the AI system. |
| Use: Laser source. |
| Advantage: The compact laser source finds application in an atom interferometer (AI) system, which may be used to measure gravity, acceleration, or rotation of the AI system. |
| Novelty: Laser source, has seed laser adapted to generate laser beam, beam splitter adapted to receive laser beam and to split laser beam into many sub-beams; and at least one channel, each channel including frequency shifter adapted to receive respective one of many sub-beams and to shift a frequency of respective one of the many sub-beams; non-linear optical element adapted to receive frequency shifted respective one of the plurality of sub-beams, to increase a frequency of frequency shifted respective one of many sub-beams, and to output the increased frequency and frequency shifted respective one of many sub-beams as a respective output laser beam; and feedback loop, feedback loop adapted to receive first of many sub-beams and to control frequency of the laser beam based upon the received first of many sub-beams, feedback loop including: feedback optical amplifier adapted to receive the first of many sub-beams and to amplify first many sub-beams; feedback non-linear optical element. |
