Mode-locked waveguide polariton laser

Optica
So far, exciton-polariton (polariton) lasers were mostly single-mode lasers based on microcavities. Despite the large repulsive polariton-polariton interaction, a pulsed mode-locked polariton laser was never, to our knowledge, reported. Here, we use a 60-µm-long GaN-based waveguide surrounded by distributed Bragg reflectors forming a multi-mode ...

Amplitude Noise and Timing Jitter Characterization of a High-Power Mode-Locked Integrated External-Cavity Surface Emitting Laser

IEEE Photonics Journal, 2014
We present a timing jitter and amplitude noise characterization of a high-power mode-locked integrated external-cavity surface emitting laser (MIXSEL). In the MIXSEL, the semiconductor saturable absorber of a SESAM is integrated into the structure of a ...

Diode-pumped 88 fs SESAM mode-locked Tm,Ho:CLNGG laser at 2090 nm

Applied Physics Express
We report on a passively mode-locked Tm,Ho:CLNGG laser operating at 2090 nm, pumped by a multimode fiber-coupled 793 nm laser diode, representing the first demonstration of a diode-pumped sub-100-fs mode-locked laser at 2.1 μ m wavelength.

Femtosecond and Dual-Wavelength Picosecond Operations of Nd,La:SrF2 Disordered Crystal Laser

IEEE Photonics Journal, 2017
Both femtosecond and dual-wavelength picosecond operations of Nd,La:SrF2 disordered crystal laser have been demonstrated for the first time. In femtosecond operation, the laser generated mode-locked pulses with pulse duration of 156 fs, which is ...

Mutually coherent dual-comb source generated from a free-running linear fiber laser

Results in Physics, 2019
We demonstrate a simple scheme for mutually coherent dual-comb generation, in which two frequency combs are emitted from a linear polarization maintaining (PM) fiber laser. The employed master laser is simultaneously mode-locked along two cross-polarized

MXene saturable absorber enabled hybrid mode-locking technology: a new routine of advancing femtosecond fiber lasers performance

Nanophotonics, 2020
MXene is a promising two-dimensional (2D) material that is widely used in electro-photonic devices due to its unique properties. In this contribution, V2CTx, a novel MXene, was employed as a saturable absorber (SA) for hybrid passively mode-locked fiber ...
