We demonstrate a broadband mid-infrared (MIR) frequency comb source based on
difference frequency generation (DFG) in periodically poled lithium niobate crystal. MIR …

We demonstrate an energy scalable approach to implement ultrafast fiber laser sources
suitable for deep tissue multi-photon microscopy imaging. Enabled by fiber-optic …

The spectral window lying between 1.6 and 1.7 μm is interesting for in-depth multiphoton
microscopy of intact tissues due to reduced scattering and absorption in this wavelength …

We report generation of sub-100 fs pulses tunable from 1700 to 2100 nm via Raman soliton
self-frequency shift. The nonlinear shift occurs in a highly nonlinear fiber, which is pumped …

A broadband high-energy all-fiber laser at 1.6-μm window with erbium-doped fiber mode
locked by nonlinear polarization rotation technology is demonstrated. The direct output …

This work explores the frequency conversion and generation of short pulses with an optical
parametric oscillator based on micro-structured fibers. Depending on the operation regime …

In the present work, we report the implementation of a novel polarization-imbalanced NOLM
for soliton cleaning. The NOLM consists of a nearly symmetrical coupler with a 51/49 …

Soliton self-frequency shift (SSFS) is a nonlinear effect that generates wavelength-shifted
laser pulses in optical fibers. Based on SSFS, we report the generation of ultrashort pulses …

We demonstrate soliton self-frequency shift (SSFS) of more than 15.5% of the optical
frequency in a phosphor-doped silica fiber for the first time. This fiber shows great potential …

We report on investigations concerning the shot-to-shot spectral stability properties of a
supercontinuum source based on nonlinear processes such as self-phase modulation and …
