Broad-Area Diode Lasers With Plane-Mirror and Phase-Conjugate Feedback
نویسندگان
چکیده
The output state of a broad-area diode (BAD) laser with phase conjugate feedback (PCF) from Rh : BaTiO3 crystal is compared to the same diode laser with conventional optical feedback from a plane mirror. A number of distinct output states, including low frequency fluctuations, are observed for each feedback type. Stable single spectral mode output is achieved with phase conjugate feedback above an injection current dependent critical level ( 20%). Conventional optical feedback from a plane mirror does not induce single-mode output at any feedback level.

Stability of a diode laser with phase-conjugate feedback.
An exact analysis is presented of the steady-state stability of a semiconductor laser subjected to feedback from a phase-conjugate mirror. Reduced stability occurs at low feedback whenever the effective external delay time is an integer multiple of the relaxation oscillation period. The role of a finite response time of the mirror is to enhance drastically the steady-state stability.
متن کاملSelf-induced frequency scanning and distributed Bragg reflection in semiconductor lasers with phase-conjugate feedback.
A GaAlAs semiconductor laser with feedback from a barium titanate photorefractive ring passive phase-conjugate mirror can be made to perform repeating or nonrepeating frequency scans over a 10-nm range toward either the blue or the red. The direction of scanning and whether the scans repeat may be controlled by adjusting the overlap of the interaction beams in the crystal. This overlap region m...
متن کاملBifurcation analysis of a semiconductor laser subject to non-instantaneous phase-conjugate feedback
We consider the question of how the behaviour of a semiconductor laser subject to phase-conjugate feedback depends on the interaction time of the phase-conjugating mirror. We employ continuation techniques to show how the bifurcation diagram in the plane of feedback strength versus pump current changes when the interaction time of the mirror is increased. This shows that for interaction times b...
متن کاملGrating Feedback in a 810 nm Broad-Area Diode Laser
Narrow linewidth, single spectral mode operation has been obtained in a high power, 810 nm broad-area diode laser in an extended cavity configuration with a grating as external reflector (grating feedback). For stable operation it was necessary to misalign the feedback slightly in the plane of the laser junction. Characteristics of the thus obtained laser system are a linewidth below 5 MHz, an ...
متن کاملLong-term stable mode locking of a visible diode laser with phase-conjugate feedback.
We present a new method to obtain long-term stable phase-conjugate feedback (pcf) with a photorefractive crystal for a mode-locked semiconductor laser. The phase-conjugate mirror is a barium titanate crystal in a self-pumped internal reflection configuration, and the laser is a visible, antireflection-coated AlGaInP diode. We describe a new dynamic writing procedure for growth of an index grati...
