SESAM (Semiconductor Saturable Absorber Mirror)
Description
SESAM (Semiconductor Saturable Absorber Mirror) mode-locked ultrafast pulsed lasers represents an important breakthrough in the development of mode-locked lasers, but a key challenge remains, that is, extending SESAM technology to the mid-infrared (MIR) region.
We propose a design based on InAs/GaSb superlattice SESAM, which can achieve over 99% reflectivity, 10%~15% modulation depth, 1.4ps-720ps flexibility in the wavelength range of 2800nm-5000nm. relaxation time and high saturation energy flow, it can achieve stable phase mode locking function.
This is the first time in the world to realize a 3-5μm ultrafast fiber laser. Its ultra-wide operating bandwidth and flexible parameter design can meet the requirements of different types of lasers in the 3-5μm band, such as fluoride fiber lasers, crystal lasers, and even 3-5μm spectral range. The application requirements of semiconductor lasers, etc., will greatly promote the development of mid-infrared ultrafast coherent sources and related application fields.
