Summary
Photocount statistics reveal significant mode fluctuations in chaotic laser resonators. Above the lasing threshold, the mean photocount distribution shows up to three distinct peaks, indicating complex emission behavior.
Area of Science:
- Optics and Photonics
- Quantum Optics
- Laser Physics
Background:
- Chaotic laser resonators exhibit complex emission properties.
- Single-mode lasing is a crucial regime for understanding laser behavior.
- Mode-to-mode fluctuations impact laser output characteristics.
Purpose of the Study:
- To derive photocount statistics for radiation from a chaotic laser resonator.
- To investigate the impact of spatial variations on laser emission.
- To analyze the photocount distribution around the lasing transition.
Main Methods:
- Derivation of photocount statistics.
- Analysis of chaotic laser resonator eigenfunctions.
- Study of single-mode lasing regime.
Main Results:
- Identified strong mode-to-mode fluctuations due to random spatial variations.
- Observed a qualitative change in mean photocount distribution at the lasing transition.
- Detected up to three peaks in the photocount distribution above the lasing threshold.
Conclusions:
- Spatial variations in chaotic resonators significantly affect laser emission.
- The photocount statistics provide insights into the lasing transition dynamics.
- The observed multi-peak distribution highlights complex photon statistics in single-mode lasing.
