what can be the output beam diameter for microchip PULSED laser in underwater lidar application?
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.
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?
Separate names with a comma.
