Hi, all.
I am a research student in laser simulation. However, i still fresh in
this area.
I have some doubt about the laser parameter relationship, like laser
intensity, laser energy, laser power, laser pulse length, laser spot
area.
Could I finalise this 5 parameters as the two formulate bellow:
1. laser spot area x laser intensity = laser power
2. laser energy / laser pulse length = laser power
In addition, could recommend me some website which will show different
laser type specification?
Thank you.

Sounds like you need to read some elementary scientific and optical
textbooks. Can anyone recommend some?
As far as your terms are concerned:
Laser intensity: I'm not sure this has a useful definition that is
independent of power.
Laser energy: This would be used for pulsed lasers to define the
energy (in Joules) per pulse.
Laser power: For a continuous wave laser this is the power in Watts.
For a pulsed lasr it is the laser energy divided by the pulse
duration. Pulse duration can be defined in many different ways.
Laser pulse length: This can be defined in many ways, the definition
varying with the pulse shape.
Laser spot area: Again this definition depends on the mode structure
of the laser.
I suggest you do some general reading on the subject.- Hide quoted text -
