Frequency stabilization of the FM laser

Proceedings of the IEEE, 1967
A technique for the frequency stabilization of an FM laser is discussed. This technique employs a stabilization discriminant derived from a residual variation of the phase and amplitude of the small FM laser beat note at the modulation frequency, as the frequency of the FM carrier moves across the Doppler gain profile.

Frequency Stabilization of a High Power Argon Laser

Applied Optics, 1972
A technique for frequency stabilizing a high power, single frequency argon laser is described which offers certain advantages over those that have already been reported. This system is capable of maintaining a relative short term frequency stability of the order of +/-2 parts in 10(9) and a long term stability (2 h) of about +/-5 parts in 10(9) for the

Frequency Stabilization of a Gas Laser

Applied Optics, 1969
The frequency of a gas laser was stabilized by making use of the competition between the oppositely circularly polarized components of a single cavity mode of a laser in an axial magnetic field. For appropriate transitions the coupling between the polarizations leads to a sharp crossover in their intensities as the cavity is tuned across the center of ...

Frequency stability and stabilization of a chemical laser

IEEE Journal of Quantum Electronics, 1978
We have built a low-power CW HF/DF chemical laser, designed to achieve high-frequency stability. Measurements are reported which characterize the instantaneous spectral width of the laser output to less than one part in 1011( \Delta\nu kHz) and the variations in absolute frequency of this emission with time to four parts in 1010( \Delta\nu = \pm20 kHz)

External dye-laser frequency stabilizer

Optics Letters, 1984
We describe an external dye-laser frequency stabilizer that combines an acousto-optic frequency shifter with a fast electro-optic phase modulator. A compensating electronic delay line in the crossover network provides a near-ideal transducer response while keeping the voltage across the electro-optic crystal away from the amplifier limits.

Frequency stabilization of a CW dye laser

IEEE Journal of Quantum Electronics, 1973
A cw dye laser system frequency stabilized to a high-finesse optical reference cavity is described. Laser frequency is servo controlled to the cavity resonance with residual fluctuations less than 50 kHz for short times (20 μsec) and 100 Hz for long times (10 sec).
