Ultrafast fiber lasers have gained rapid advances in last decades for their intrinsic merits
such as potential of all-fiber format, excellent beam quality, superior power scalability, and …

Optical frequency combs have revolutionized optical frequency metrology and are being
actively investigated in a number of applications outside of pure optical frequency metrology …

This paper reviews the scientific contributions of the last 30 years on erbium-doped fiber
laser ultrashort pulse generation in South America. The focus is on contributions authored in …

We report an Er-doped fiber laser based on a hybrid mode-locked mechanism, which
include a graded-index multimode fiber as a saturable absorber (SA) and nonlinear …

In this work, we present a detailed experimental study of pulse formation mechanism in an
EDFL, hybridly mode-locked by use of a CVD monolayer graphene onto a D-shaped optical …

We proposed a hybrid passive mode-locked fiber laser based on a saturable absorber
fabricated by coating a layer of graphene on a single-mode fiber with inscribed short …

Supercontinuum generation via direct pumping of unamplified high-repetition-rate, sub-100
fs pulses with a pulse energy lower than 50 pJ is superior in noise performance and features …

We demonstrate a robust femtosecond LIDAR setup by using two free-running
environmentally stable all-polarization-maintaining nonlinear amplified loop mirror mode …

We experimentally investigated the saturable absorption influence of graphene layers with
natural stacking order in an erbium-doped fiber laser passive mode-locking. Mechanically …

The absolute group refractive index of air at 1563 nm is measured by dispersive
interferometry, and a combined uncertainty of 1.2× 10^− 8 is achieved. The group refractive …
