Title: Effects of optical feedback in a birefringence-Zeeman dual frequency laser at high optical feedback levels

Abstract

Optical feedback effects are studied in a birefringence-Zeeman dual frequency laser at high optical feedback levels. The intensity modulation features of the two orthogonally polarized lights are investigated in both isotropic optical feedback (IOF) and polarized optical feedback (POF). In IOF, the intensities of both beams are modulated simultaneously, and four zones, i.e., the e-light zone, the o-light and e-light zone, the o-light zone, and the no-light zone, are formed in a period corresponding to a half laser wavelength displacement of the feedback mirror. In POF, the two orthogonally polarized lights will oscillate alternately. Strong mode competition can be observed, and it affects the phase difference between the two beams greatly. The theoretical analysis is presented, which is in good agreement with the experimental results. The potential use of the experimental results is also discussed.

  • A new, incoherent, optical negative feedback method is proposed and demonstrated for spectral linewidth reduction and optical frequency stabilization of distributed feedback lasers. The spectral linewidth and the optical frequency drift are simultaneously reduced to about 50 kHz and less than 10 MHz, respectively.
  • A general optical model is given which predicts optical wave front distortions and birefringence due to stress and temperature variations in laser heated and pressure loaded windows for cubic lattice window materials. A computer code is described that integrates stress and thermal computations with an optical model to predict the wave front distortions. Restrictive approximations, which have been used previously to predict window temperatures and stress distributions, are avoided by using stress and thermal codes to predict these distributions within the windows. Comparisons between code predictions and experimental results are given.
  • An intracavity HeNe birefringent dual-frequency laser is investigated for applications. The substrate of such a laser cavity mirror is made of quartz crystal instead of ordinary optical glass. The surface that functions as the laser cavity mirror is coated with a high-reflecting thin film layer, while the surface joined to the discharge tube is coated with an antireflecting thin film layer. Thus, the laser is an intracavity laser and the quartz crystal located inside the cavity causes the longitudinal mode to split into two modes (frequencies). To obtain the appropriate design parameters for various frequency differences, a series of quartzmore » crystal cavity mirrors with different cut angles is experimentally investigated. The relationship of mode splitting and the cut angle are observed. To estimate the splitting by one mirror for different cavity lengths, the following concepts are presented: relative mode (frequency) splitting (ration of mode splitting versus longitudinal mode spacing) and relative optical path difference (ration of optical path difference versus half-wavelength).« less
  • Enhanced intensity fluctuations, in particular the low-freqeuncy fluctuation (LFF) component, which appear in a semiconductor laser-diode (LD) output with external optical feedback, can have seriously adverse effects in practical applications when they fall within the signal bandwidth. Experiments have been carried out to determine the mechanism of the LFF enhancement, and a simple relationship between its peak frequency f/sub 0/ and the basic parameters characterizing an LD with an external reflector have been established. The resuts are in qualitative agreement with the prediction based on a compound cavity laser model.
