Abstract:

Lifetime measurements of the excited states of three GaAs semiconductors doped with the rare earth elements Erbium ER, Praseodymium Pr , and Thulium Tm has been studied using a pulsed nitrogen laser and germanium detector. The measurements were made with an experimental set up with a system response time of 0.34 micro seconds. A 330 milliwatt nitrogen laser with a wavelength of 3370 angstrums was used to excite transitions of the rare earth elements.
