Intensity Dependent Nonlinear Absorption in Direct and Indirect Band Gap Crystals under Nano and Picosecond Z-Scan
Direct and Indirect Band Gap Crystals Two Photon Absorption Three Photon Absorption Saturated Absorption
2013/1/30
The nonlinear absorption properties of direct (GaN) and indirect (CdI2) band gap crystals have been studied by using an open aperture Z-scan technique under fundamental (1064 nm) and frequency doubled...
Mode-Locking Nano-Porous Alumina Membrane Embedded with Carbon Nanotube Saturable Absorber
Alumina Membrane Embedded Carbon Nanotube Saturable Absorber
2015/7/30
Carbon nanotube saturable absorber was embedded in funnel-shaped nanoporous alumina to reduce heat-up problem drastically. Actually, it induced stable mode-locking of Er fiber laser over 3 months.
