Continuous wave dual-wavelength operation at 1048 and 1386 nm in Nd<sup>3+</sup>:LaBGeO<inf>5</inf> for yellow laser light generation
We present results on simultaneous oscillation in continuous-wave at 1048 and 1386 nm in Nd3+:LaBGeO5 crystal. LaBGeO5 is a nonlinear positive uniaxial crystal with potential application for intracavity generation of yellow laser radiation at 597 nm. Due to the different cross section in both laser channels, simultaneous oscillation is achieved by axial hole burning in a standing wave (linear cavity). It is concluded that a stable output laser spectrum is obtained for an absorbed pump power of 700 mW. A laser competition with alternating single-channel and dual-channel oscillation at different pump regimes was observed in the experiments.
Fully automatic simultaneous fibre grating amplitude and group delay characterization
We present a novel fiber grating measurement technique based on the direct modulation of a tunable laser source by an optical component analizer.
