Hi guys,
I am of a Mechanical Engineering background, however my dissertation has a largely optics based focus, and I am struggling with understanding the heating effect of a Laser.
I will be using various wavelength ND:Yag lasers, and will be focussing them onto a target material, which I have not yet decided upon. I need to be able to calculate the heating effect of the laser on this material.
For example, if I pulse the laser constantly for 2 seconds, what will be the temperature increase of the material?
For arguement's sake, we could consider the laser to be of these specifications:
Dimensions
Laser transmitter 325 x 201 x 119 mm
Laser receiver 105 x 77 x 23 mm
Mass
Laser transmitter < 7.5 kg
Laser receiver < 0.5 kg
Aperture
10 mm
Beam Divergence
Tactical @ 1.06 μm < 1 mRad
Output Energy
< 300 mJ @ 1.06 μm
< 90 mJ @ 1.57 μm
Repetition Rate
20 Hz (on both wavelengths)
Average Power
< 325 W
Thank you very much for your input.
