Verifying Laser Parameters
Verifying Laser Parameters
(OP)
Hi,
I was wondering what methods exist to verify the laser parameters of a Nd:YAG laser. Basically if I'm firing on a sheet of metal is there a quick way to makes sure that frequency, speed and power are correct (the same as the laser claims them to be).
This might be a really basic question but I'd be really interested what ways you use to ensure the parameters are the same as the laser claims them to be.
Thanks a lot!

RE: Verifying Laser Parameters
Thank you for your quick response. Yeah I have got all the default parameters. My question concerns more how I can verify them. E.g. if I'm setting my laser to a frequency of 40 kHz how can I verify that it is actually firing with 40 kHz and not with 38 or something similar.
I hope this is more clear now ;).

Then look at the docs, and figure out where you can monitor the firing signal that drives the excitation system. (flashlamps, I imagine)
or, some way to look at the flash of the pulsed beam on some material and time that.
Monitor a Photodiode with a frequency counter?
For other parameters, it could be trickier. But in truth, why do you care if it is exactly some frequency?

RE: Verifying Laser Parameters
thanks for your suggestions. I'll have a look at that.
Urm, it's just for an experiment as this is a newly purchased laser and I had the feeling some parameters are not what they are supposed to be.
Thanks again!
