Paper About Development of Time Resolved Energy Absorption Measurement Technique for Laser Beam Spot Welds

Lots of information such as laser beam, the beam splitter, energy distribution, calibration, and beam splitter are explained in this paper. This paper contains info about time, photodiode, transfer efficiency, measurement, and measurement technique.

In this paper we can learn things such as measurements, parameters, laser pulse, energy transfer, and method. Below are taken from this paper:

Norris Supplement April 2010:Layout 1 3/10/10 2:37 PM Page 75 Development of a Time-Resolved Energy Absorption Measurement Technique for Laser Beam Spot Welds By relating the instantaneous delivered power and pulse energy to the scattered power during welding, a time-resolved description of the power and energy absorption can be obtained ABSTRACT A method has been developed to temporally characterize the power and energy absorbed in laser beam spot welding (LBSW).

Even more, this paper gives you more around absorption, sphere calibration, efficiency, and waveform.
