Laser engineering – Common used five optic elements in laser beam delivery engineering

By function, the laser beam delivery systems can be classified into focusing, collimation, beam expansion, deflection, and splitting.

Laser study – Key parameters of pulsed laser for material processing

The key parameters of a pulsed laser—pulse width, repetition rate, and pulse energy—each affect material processing quality in different ways.

Laser engineering – How to control the output power of laser source?

The typical 3 control methods are: adjusting the pump power; duty cycle modulation, and
change the intensity of dye or chemical.
