Jul 09, 2016· The basic operation is as follows. The laser diode is forward-biased by an external voltage source. As electrons move through the junction, recombination occurs just as in an ordinary diode. As electrons fall into holes to recombine, photons are released. A released photon can strike an atom, causing another photon to be released.
Clinical applications of the CO2 and diode lasers on soft tissues, particularly in the fields of oral and maxillofacial surgery and perodontics, are explained.
