Mode-locking of an Er:Yb:glass laser with single layer graphene

All solid‐state pulsed lasers (ASSPLs) play a significant role in the fields of medical, military, industry, and scientific research. Passive Q‐switching and mode‐locking are two of the most effective techniques for generating ASSPLs, in which a saturable absorber (SA) is the key element that has great impact on laser output parameters. Recently, 2D layered materials have been widely studied due to their intriguing properties. Their advantages of ultrafast dynamic processing, excellent nonlinear optical response, broadband operation, and easy fabrication and integration with lasers, enable them to be excellent SAs. Herein, the recent progress of ASSPLs with 2D layered material‐based SAs is reviewed, including a brief introduction of the fundamental characteristics, fabrication methods, characterization techniques of ultrafast dynamics, and nonlinear optical properties of 2D materials, design criteria of passively Q‐switched and mode‐locked bulk lasers, and their applications in ASSPLs. Finally, the potential developments and perspectives on 2D material‐based ASSPLs are also highlighted.

Weak polarization dependence based on evanescent field interaction with a monolayer graphene absorber is demonstrated. By covering single-layer graphene on the top of a fiber taper, the symmetry of the light field propagation was destroyed. Polarization-dependent loss (PDL) of 2 dB was obtained, and no saturable absorption was observed. Passive mode locking was achieved by using the graphene-covered fiber taper in a fiber laser. It is found that the weak PDL down to 2 dB is capable for achieving mode locking in a fiber laser. Therefore, the claim of saturable absorption of any graphene or two-dimensional materials in a fiber laser needs to be made with care.

Mode-locking of an Er:Yb:glass laser with single layer graphene

Abstract: 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.
