FREQUENCY STABILIZATION OF THE ZEEMAN LASER
Applied Physics Letters, 1967The intensity crossover region with cavity tuning between oscillations on two orthogonally circularly polarized axial modes of a Zeeman laser has been used to stabilize these oscillation frequencies with respect to the center of the atomic transition.

Frequency Stabilization of Semiconductor Lasers
2017Stability of laser frequency is one of the most important performances. The frequency stabilization involves basically three parts: a reference frequency, i.e., the target frequency the laser frequency is to be locked, a frequency discriminator, and a method of feedback to tune the laser. The absorption lines of atoms or molecules are mostly often used

Frequency stabilization in semiconductor lasers
Optical and Quantum Electronics, 1988Three promising methods of improving temporal coherence in semiconductor lasers are reviewed. They are the development of novel laser devices, a technique of optical feedback and a technique of electrical feedback. The main discussion in this paper is focused on the technique of electrical feedback.

Increasing the frequency stability of single-frequency lasers
Review of Scientific Instruments, 1993We have developed an improved technique to increase the stability of single-frequency lasers by employing a scanning Fabry–Perot interferometer and a stabilized helium neon laser. Our instrument surpasses earlier devices in several key areas. The laser frequency can now be stabilized while scanned across its inherent single-frequency tuning range.

Frequency stabilization of frequency-doubled Nd:YAG lasers at 532 nm
1998 Conference on Precision Electromagnetic Measurements Digest (Cat. No.98CH36254), 2002We report the preliminary results on the frequency stabilization of two frequency-doubled diode-pumped Nd:YAG lasers to hyperfrne structure components of the rovibrational transition P(54)32-0 of I-127(2) with the sub-Doppler sidebands method In a preliminary experiment, we have obtained a relative frequency stability of 2.9 .

Intermode beat stabilized laser with frequency pulling
Applied Optics, 1994A frequency-stabilized two-mode He-Ne laser has been developed. The intermode beat frequency of the experimental laser was approximately 600 MHz for a 25-cm cavity. The laser frequency in which the mode stands is pulled to the center of the gain curve (frequency pulling).
