Optics Express
|April 7, 2017
Summary
Distortions in time-domain pulsed echo laser profiles (TDPELP) occur due to receiving lens (RL) position changes. Adjusting RL focal length with a tunable lens corrects these distortions for optimal TDPELP.
Area of Science:
- Optics
- Laser Physics
- Experimental Physics
Background:
- The time-domain pulsed echo laser profile (TDPELP) is crucial for laser-based measurements.
- Understanding factors affecting TDPELP quality is essential for accurate data acquisition.
Purpose of the Study:
- To investigate the impact of receiving lens (RL) positioning on TDPELP.
- To develop a method for optimizing TDPELP under varying intensity conditions.
Main Methods:
- Theoretical analysis of RL defocus, off-axis, and tilt effects.
- Experimental validation of TDPELP distortions.
- Utilizing a tunable lens to adjust RL focal length.
Main Results:
- RL position variations (defocus, off-axis, tilt) cause TDPELP distortions like saturation and broadening.
- These distortions are independent of the specific RL position.
- Tunable lens adjustment successfully optimized TDPELP in extreme intensity scenarios.
Conclusions:
- RL positioning significantly impacts TDPELP quality.
- Tunable lens technology offers a viable solution for correcting TDPELP distortions.
- Optimized TDPELP is achievable even under challenging experimental conditions.
