Frequency stabilization in semiconductor lasers

Optical and Quantum Electronics, 1988
Three 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.

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).

Frequency stabilization of frequency-doubled Nd:YAG lasers at 532 nm

1998 Conference on Precision Electromagnetic Measurements Digest (Cat. No.98CH36254), 2002
We 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 .

Increasing the frequency stability of single-frequency lasers

Review of Scientific Instruments, 1993
We 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 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)

FREQUENCY STABILIZED TUNABLE LASER TECHNOLOGY

Integrated Photonics Research, 1999
This paper describe two approaches for achieving frequency stabilized laser module with 7 and 18 channels tunability capability on a 100 GHz spacing. Discussion on the evolution of the technology to 36 channels will be made.

Frequency stabilization of gas lasers

Proceedings of the IEEE, 1967
Methods of frequency and wavelength stabilization of gas lasers are reviewed with emphasis on principles of operation and results of stability measurements rather than experimental details or apparatus design. Most of the stabilization work has been done with the He-Ne laser. The best long-term stability is about 1 part in 109.
