A 1.55µm Er glass laser pumped by a 1.06µm Nd:YAG laser
A 1.55µm Er glass laser pumped by a 1.06µm Nd:YAG laser
The current interest in optical communication systems operating around 1.5µm has generated a requirement for coherent sources in this spectral region. Given the variety of measurements and investigations to which such sources would be applied, there is a need for a convenient versatile source, capable of operating cw, pulsed, mode-locked and Q-switched. With such a source in mind; we have looked at the possibilities of an Er glass laser pumped by a Nd:YAG laser. In this paper we report the preliminary results of lasing at 1.54µm from a commercially available Er glass rod pumped by a pulsed Nd:YAG laser. The performance data indicate that cw lasing using a cw Nd:YAG laser should also be possible, and that a fibre laser based on this same glass should have a very low threshold, compatible with pumping by a diode-pumped miniature Nd:YAG laser.

Abstract
The current interest in optical communication systems operating around 1.5µm has generated a requirement for coherent sources in this spectral region. Given the variety of measurements and investigations to which such sources would be applied, there is a need for a convenient versatile source, capable of operating cw, pulsed, mode-locked and Q-switched. With such a source in mind; we have looked at the possibilities of an Er glass laser pumped by a Nd:YAG laser. In this paper we report the preliminary results of lasing at 1.54µm from a commercially available Er glass rod pumped by a pulsed Nd:YAG laser. The performance data indicate that cw lasing using a cw Nd:YAG laser should also be possible, and that a fibre laser based on this same glass should have a very low threshold, compatible with pumping by a diode-pumped miniature Nd:YAG laser.
