Dysprosium-doped ZBLAN fiber laser tunable from 2.8 {\mu}m to 3.4 {\mu}m, pumped at 1.7 {\mu}m

, 2018
We demonstrate a mid-infrared dysprosium-doped fluoride fiber laser with a continuously tunable output range of 573 nm, pumped by a 1.7 {\mu}m Raman fiber laser. To the best of our knowledge, this represents the largest tuning range achieved to date from

Design Considerations for Continuous Wave Intracavity Backwards Optical Parametric Oscillators

Photonics
In this paper, we report a theoretical systematic study of continuous wave intracavity backwards optical parametric oscillators based on periodically poled lithium niobate (PPLN) for mid-infrared (mid-IR) light generation. We study the effects of varying

Estimating optical feedback from a chalcogenide fiber in mid-infrared quantum cascade lasers

AIP Advances, 2016
The amount of optical feedback originating from a chalcogenide fiber used to couple light from a mid-infrared quantum cascade laser is evaluated experimentally. Threshold reduction measurements on the fibered laser, combined with an analytical study of a

Femtosecond Photodissociation of Molecules Facilitated by Noise

, 2007
We investigate the dynamics of diatomic molecules subjected to both a femtosecond mid-infrared laser pulse and Gaussian white noise. The stochastic Schr\"odinger equation with a Morse potential is used to describe the molecular vibrations under noise and

Population Redistribution among Multiple Electronic States of Molecular Nitrogen Ions in Strong Laser Fields

, 2015
We carry out a combined theoretical and experimental investigation on the population distributions in the ground and excited states of tunnel ionized N2 molecules at various driver wavelengths in the near- and mid-infrared range.
