Chapter 9 Laser Pulses Characterization with Pyroelectric Sensors
There are many industrial and medical applications of CO2 (λ=10.6 μm) and Nd:YAG (λ=1.06 μm) infrared lasers for which the quality of the process are tightly connected to the characteristic of the laser pulse. These two types of lasers deliver pulses with duration, repetition frequency and pow...

| description | There are many industrial and medical applications of CO2 (λ=10.6 μm) and Nd:YAG (λ=1.06 μm) infrared lasers for which the quality of the process are tightly connected to the
characteristic of the laser pulse. These two types of lasers deliver pulses with duration,
repetition frequency and power that can be controlled by means of a programmable
electronic control unit. An open-loop control generally optimize the process performances
by availing of a laser system model. However, this method cannot control that during the
operation the laser source and the optical delivering system could deteriorate; moreover
the laser beam characteristics and laser pulse temporal envelope could change by several
factors like power supply variations, optical beam misalignments, dirty deposits on mirrors,
changes in laser efficiency and many others . |
