Mode-locking of an Er:Yb:glass laser with single layer graphene
نویسندگان
چکیده
Pulses as short as 260fs have been generated in an Er:Yb:glass laser by saturable absorber mode-locking using graphene as the only mode-locking mechanism. These novel saturable absorbers present a low-cost, ultra-broadband alternative to traditional SESAMs.

11-GHz waveguide Nd:YAG laser CW mode-locked with single-layer graphene
We report stable, passive, continuous-wave (CW) mode-locking of a compact diode-pumped waveguide Nd:YAG laser with a single-layer graphene saturable absorber. The depressed cladding waveguide in the Nd:YAG crystal is fabricated with an ultrafast laser inscription method. The saturable absorber is formed by direct deposition of CVD single-layer graphene on the output coupler. The few millimeter-...
متن کامل科学网博客-[转载]Graphene and Lasers Become Ultrafast Friends
Ultrafast laser sources have garnered considerable attention for their many potential applications, ranging from meteorology to telecommunications, medicine, and materials processing. Most of these lasers employ a mode-locking technique in which a nonlinear optical element, called a saturable absorber,turns the laser's continuous wave output into a train of ultrashort optical pulses. Currently,...
متن کاملUltra-short Optical Pulse Generation with Single-layer Graphene
Since the first report of single-layer graphene a few years ago, this material has already proven to possess a great number of interesting properties. One of these properties is its non-linear optical behavior, namely its wavelength-independent saturation of optical absorption. This saturable absorption can be utilized to induce self-amplitude modulation in a laser cavity, thus mode-locking las...

We demonstrate mode locking of a thulium-bismuth codoped fiber laser (TBFL) operating at 1901.6 nm, using a graphene-based saturable absorber (SA). In this work, a single layer graphene is mechanically exfoliated using the scotch tape method and directly transferred onto the surface of a fiber pigtail to fabricate the SA. The obtained Raman spectrum characteristic indicates that the graphene on...
متن کاملEffects of flake size on mode-locking behavior for flake-graphene saturable absorber mirrors
After advent of graphene as a saturable absorber many experiments have been conducted to produce short pulse duration pulses. Here, we have measured the properties of flake-graphene saturable absorber mirrors of various flake sizes dependent on fabrication technique. These mirrors enabled us to obtain a large mode-locking bandwidth of 16nm in an erbium-doped fiber laser. Mirrors with large flak...
