Wavelength tuning in Er3+,Yb3+:glass microchip lasers

Abstract

The paper presents the investigation results of laser generation around 1.5 μm at different wavelengths. The shifts of the wavelength were achieved by the change of pump power, transmission of an output mirror, and length of an active medium. Mathematical analysis and explanation of this phenomenon was curried out on the basis of the change in relation between the gain and loss lines. © 2009 © Versita Warsaw and Springer-Verlag Berlin Heidelberg.
