Journal ArticleDOI
Graphene mode-locked femtosecond Cr:ZnSe laser at 2500 nm
TL;DR: This is the longest laser wavelength at which graphene-based passive mode-locking has been demonstrated to date and it is reported, for the first time, femtosecond pulse generation from a graphene mode-locked Cr:ZnSe laser at 2500 nm.
Journal ArticleDOI
High-quality, large-area monolayer graphene for efficient bulk laser mode-locking near 1.25 μm.
Won Bae Cho,Jun Wan Kim,Hwang Woon Lee,Sukang Bae,Byung Hee Hong,Sun Young Choi,In Hyung Baek,Kihong Kim,Dong-Il Yeom,Fabian Rotermund +9 more
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.
