Vector Soliton Fiber Laser With Atomic Layer Graphene
... Except the conventional semiconductor saturable absorber mirrors (SESAMs), which use III–V semiconductor multiple quantum wells grown on distributed Bragg reflectors (DBRs),many researchers have ... But there had been no alternative saturable absorbing materials to compete with SESAMs for the passive mode-locking of fiber lasers ... Recently, by the virtue of the saturable absorption properties in single wall carbon nanotubes (SWCNTs) in the near-infrared region with ultrafast saturation recovery times of ~1 picosecond, researchers have ...
Mode-locking Methods - Passive Mode-locking
... A commonly used device to achieve this is a saturable absorber ... A saturable absorber is an optical device that exhibits an intensity-dependent transmission ... For passive mode-locking, ideally a saturable absorber will selectively absorb low-intensity light, and transmit light which is of sufficiently high intensity ...
Quantum Well - Applications
... Quantum well can be fabricated as saturable absorber utilizing its saturable absorption property ... Saturable absorber is widely used in passively mode locking lasers ... Semiconductor saturable absorbers (SESAMs) were used for laser mode-locking as early as 1974 when p-type germanium is used to mode lock a CO2 laser which generated pulses ~500 ps ...
