Boosting the Non Linear Optical Response of Carbon Nanotube Saturable Absorbers for Broadband Mode-Locking of Bulk Lasers

Won Bae Cho, +10 more
- 23 Jun 2010 - 
TL;DR: In this paper, single-walled carbon-nanotube absorbers are used for laser mode-locking and shown to exhibit low saturation fluence of <10 mu J cm(-2), low scattering losses, and an exceptionally rapid relaxation, with time constants reaching <100 fs.
Journal ArticleDOI

Ohmic contact formation mechanism of Ni on n-type 4H–SiC

Sang Youn Han, +7 more
- 12 Sep 2001 - 
TL;DR: Ohmic contact formation mechanism of Ni on n-type 4H-SiC is proposed by comparing the electrical properties with microstructural change as discussed by the authors, showing that a number of carbon vacancies were produced below the contact, playing a key role in forming an ohmic contact through the reduction of effective Schottky barrier height.
Journal ArticleDOI

High-quality, large-area monolayer graphene for efficient bulk laser mode-locking near 1.25 μm.

Won Bae Cho, +9 more
- 15 Oct 2011 - 
TL;DR: High-quality monolayer graphene as large as 1.2×1.2 cm2 was synthesized by chemical vapor deposition and used as a transmitting saturable absorber for efficient passive mode-locking of a femtosecond bulk solid-state laser.
Journal ArticleDOI

Fabrication and characterization of ultrafast carbon nanotube saturable absorbers for solid-state laser mode locking near 1μm

Jong Hyuk Yim, +9 more
- 21 Oct 2008 - 
TL;DR: In this paper, a single-walled carbon nanotubes (CN) is used to reflect ultrafast saturable absorbers for stable mode locking of bulk solid-state lasers operating near 1μm.
Journal ArticleDOI

Graphene-filled hollow optical fiber saturable absorber for efficient soliton fiber laser mode-locking.

Sun Young Choi, +6 more
- 27 Feb 2012 - 
TL;DR: A novel in-line saturable absorber based on hollow optical fiber filled with graphene composite for high power operation of mode-locked fiber laser that enables robust and efficient nonlinear absorption leading to stable passive mode-locking.
