What is the difference between diode laser and fiber laser
Fiber lasers do not require as much energy as CO2 lasers. Instead, they operate at a shorter wavelength (780 nm to 2220 nm), giving them a much higher absorption.
But we all know cost does not just stop when you first buy a laser machine. Both laser and plasma have cost associated with them for operating and maintenance. Things you need to consider are stuff like power consumption, maintenance, consumables, and labor (how much time/money it cost to operate the machine).
