Ultrafast fiber laser at 1570 nm based on organic material as saturable absorber

Scientific Reports, 2022
In this work, we demonstrated Poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS) as a saturable absorber (SA) to produce mode-locking operation in different length of Erbium-doped fiber laser (EDFL).

Clinical and histological evaluation of a dual sequential application of fractional 10,600 nm and 1570 nm lasers, compared to single applications in a porcine model

Lasers in Medical Science, 2021
The sequential application of fractional ablative/10,600 nm/CO 2 followed by 1570 nm non-ablative laser treatment might produce better results than applying either laser treatment alone. However, histological data regarding the safety of this combination
