Laser in underwater lidar application?

Click For Summary

Discussion Overview

The discussion revolves around the application of microchip pulsed lasers in underwater lidar systems, specifically focusing on the output beam diameter and related parameters such as polarization and output power.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions the existence of a definitive answer regarding the output beam diameter for a microchip pulsed laser in underwater lidar applications.
  • Another participant suggests that the output beam diameter could be represented as \(\pi/e\), while also indicating that it could vary.
  • A further inquiry is made about the meaning of "e" in this context, questioning whether it refers to the charge or the exponential constant.
  • Additional questions are raised regarding the type of polarization and output power suitable for pulsed laser sources in underwater lidar applications.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, with multiple competing views and questions remaining unresolved.

Contextual Notes

There are limitations in the discussion, including the lack of specific parameters and definitions needed to clarify the questions raised about the laser's output characteristics.

what can be the output beam diameter for microchip PULSED laser in underwater lidar application?
 
Science news on Phys.org
I do not think that an answer exits for the given information.
 
It can be [itex]\pi/e[/itex].
It can be something else too.
 
laser

what does e specify?e charge or exp const?
what type of polarization&output power for pulsed laser source can be used in lidar application under sea?
