Generation of tunable q-switched erbium-doped fiber laser based on graphite flakes saturable absorber [PDF]

open access: yes, 2020
Pulsed fiber laser has tremendous application in laser processing and laser sensor. The key element to produce a passively Q-switched fiber laser is by using a saturable absorber (SA).

Functional tomography using a time-gated ICCD camera

open access: yesBiomedical Optics Express, 2011
We present a system for near infrared functional tomography based on a single pulsed source and a time-gated camera, for non-contact collection over a large area. The mean penetration depth of diffusely reflected photons is dependent on the arrival time of photons, but not on the source-detector distance.
