摘要： A method for determining saturated absorption lines includes defining (ST2A) first and second threshold values based on an output value of a light output signal. The first and second threshold values are in a magnitude relationship. An output value of a second-order differential signal of the light output signal is compared with the first and second threshold values. A determination is made as to whether the second-order differential signal following a change in a resonator length has an output waveform that displays a behavior in which the output waveform changes from less than the second threshold value to be equal to or greater than the first threshold value, and then changes to be less than the second threshold value. Based on a result of the determination by the waveform determination, a determination is made as to whether the output waveform of the second-order differential signal is the saturated absorption line (ST2C).

摘要： A smart laser having automatic computer control (24A) of pulse energy, wavelength, and bandwidth using feedback signals from a wavemeter (22). Pulse energy is controlled by controlling discharge voltage. Wavelength is controlled by very fine and rapid positioning of an Rmax mirror in a line narrowing module. Bandwidth is controller by adjusting the curvature of a grating in the line narrowing module. Preferred embodiments include automatic adjustment of a prism plate on which beam expander prisms are located and automatic adjustment of the Rmax tilt. Other preferred embodiments include automatic adjustment of the horizontal position of the laser chamber (3) within the resonance cavity. In preferred embodiments, feedback signals from a wavelength monitor are used to position the Rmax mirror. In other embodiments a separate laser beam reflected off the Rmax mirror on to a photodiode array is used to position the mirror.

摘要： Windshear detector using Rayleigh-backscattered light and a molecular filter for optical discrimination, and frequency locking of a laser, to detect windshear. The windshear detector has a pulsed ring laser that transmits a signal out of the detector and receives reflected backscatter of the transmitted signal. The ring laser is driven with an injection laser. Both lasers are ultimately keyed to the molecular transmission or absorption filter with locking electronics. The received reflected backscatter is detected and processed into a signal that indicates whether there is windshear or turbulence.

摘要： @ There is disclosed a dual-wavelength laser apparatus including a laser emitting a laser beam consisting of two wavelength components, a methane cell for controlling and equalizing gains of the two wavelength components, a cavity length modulator including a piezoelectric element for periodically modulating the cavity length of the laser, and a feedback circuit for controlling the modulation center such that the sum of outputs of the two modulated wavelength components is kept substantially constant. The feedback circuit includes a detector for detecting a laser output, a lock-in amplifier for detecting and amplifying an output from the detector, an integrator for integrating an output from the lock-in amplifier, and a high-voltage amplifier for generating a bias voltage set by the integrator.

摘要： Embodiments of an ultra-stable frequency reference generating system and methods for generating an ultra-stable frequency reference using a two-photon Rubidium transition are generally described herein. In some embodiments, a cavity-stabilized reference laser comprising a laser source is locked to a stabilized cavity. A Rubidium cell is interrogated by a stabilized laser output to cause at least a two-photon Rubidium transition and a detector may detect fluorescence resulting from spontaneous decay of the upper state Rubidium transition. The output of the detector is provided at a wavelength of the fluorescence to lock the cavity-stabilized reference laser to generate a stabilized laser output. A frequency comb stabilizer may be locked to the stabilized laser output to generate a super-continuum of optical wavelengths for use in generating an ultra-stable frequency reference.
