The 0.005” holes were drilled in 0.020” thick Stainless Steel using an Evolution 125 laser with 40psi oxygen assist gas and optical set up providing a 0.005” spot size.  The laser was pulsed at 750Hz with a pulse length of 240 microseconds giving an average power of 30W. The holes required 55 pulses giving a cycle time of 73 microseconds per hole.  


These holes were created using an Evolution 125 laser.
