Summary

The elements for controlling generation impulse length of ruby and neodymium lasers were made using CdP₂ monocrystal as a non-linear sealed beam.

Description

The extenders of laser irradiation impulses within the range of 20–350 ns were developed owing to nonlinearity light absorption, based on CdP₂ monocrystal.

Technical advantages and economic benefits

Due to use of CdP₂ based extenders the impulse length may be increased from 20-25 to 150-350 ns. At the same time, as opposed to wide use of GaAs, CdAs, CdS crystals, cupped impulse form remains unchanged confirming fast Q-switching.
