Hi all.
I am new to CO2 laser cutting world and don't have much experience.
Right now, I am working in a project "60w co2 laser cutting machine".
For this project, I have selected Synrad's Firestar ti60 series laser. The output diameter of lase is 2mm +-0.3mm and beam divergence is full angle 7mrad. Laser module in machine remains stationary and focusing lens will be placed in the moving x and y axis. So definitely, I should reduce the divergence angle to zero so that when my focus lens moves in the x-y plane, laser diameter that strikes on the lens remains stable. (Laser diameter remains constant.)
For such problem, as my knowledge I need to place a collimator right after the laser exit and before the first deflecting lens.
To apply this method which beam collimator I should use?
Any one have any idea about it?
Should I go with variable beam expander with collimator or with fixed one ?
Please help me guys.
For the reference, I have attached specification sheet of the Firestar ti60 series laser.
