Responsiveness of temperature using tunable dual-wavelength Q-switched fiber laser

In this paper, a responsiveness temperature based on a tunable dual-wavelength Q-switched fiber laser has been proposed and experimentally demonstrated. Experiments have been carried out with tunable dual-wavelength Q-switched fiber laser by using graphite as a saturable absorber, which is incorpor...
