Frequency Stabilized Hard x Ray Lasers
2022 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR), 2022By using Bragg condition inside x-ray laser medium, we have succeeded to achieve distribution feedback type laser in hard x ray region. We also use crystal lattice constant so that it is possible to demonstrate the first frequency stabilized hard x ray lasers.

External dye-laser frequency stabilizer
Optics Letters, 1984We 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-stabilized laser-diode-pumped Nd:YAG laser
Optics Letters, 1989We describe a frequency-stabilized diode-pumped Nd:YAG laser that is actively frequency stabilized relative to a reference Fabry-Perot cavity using the Pound-Drever technique. We describe the servo loop and the measurement of its noise and gain performance and demonstrate its ability to reduce the laser frequency noise close to the shotnoise limit of ...

Frequency-stabilized Diode Lasers
LEOS '92 Conference Proceedings, 2005We will review the state-of-the-art in frequency stabilized diode lasers and methods to characterize laser linewidth and stability. Progress with frequency/wavelength references in the near visible region (Ca, Rb, Cs, and Sr) will be presented.

Frequency Stabilization of a Gas Laser
Applied Optics, 1969The 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 ...

Laser frequency stabilization using forward scattering
Proceedings of 5th European Quantum Electronics Conference, 1994Frequency stabilization of a single-mode dye laser is demonstrated using a simple magneto-optical forward scattering method. The dye laser was locked to the 2p4−3ss2, λ = 633 nm neon transition. Heterodyne beat-frequency measurements against a127I2-He-Ne meter standard laser showed a frequency stability of a few MHz.

Frequency stability of a Zeeman-stabilized laser
Applied Optics, 1985The frequency of a commercial hard-sealed He–Ne laser has been stabilized to the center of the discharge gain profile using the mode splitting caused by an axial magnetic field. The absolute frequency has been measured repeatedly during intermittent operation over 20 months. Its drift over most of this period has been 2.6 ± 0.7 MHz/yr.

Optogalvanic Laser Frequency Stabilization
1986The CO2 laser radiation field intensity is large enough and when is varied it introduces significant changes in the laser plasma microscopic parameters such as discharge sidelight intensity, plasma impedance and gas temperature. From among these parameters, a distinct interest is given to plasma impedance, because it is possible to establish a direct ...

Laser-frequency division and stabilization
Physical Review A, 1984The current method for measuring an optical frequency relative to the primary time standard, the cesium beam standard at ~9.2 GHz, utilizes a complex frequency synthesis chain involving harmonics of laser and klystron sources. The method has been extended recently to the visible region,1 to the 633 nm He-Ne laser locked to a molecular iodine line, with
