We propose an integral imaging system that uses three lens arrays, including two convex lens arrays and a concave lens array. Compared with the conventional integral imaging system, the proposed system can remarkably enhance the viewing angle. The maximum
A laser diode-pumped high-efficiency widely tunable Tm:YAP laser with excellent comprehensive properties is reported. The output power is stable at a given pump power. Under the absorbed pump power of 12.95 W, the maximum output power at 2,010 nm is 5.16
The electron thermalization and relaxation processes in ferromagnetic nickel thin film and micro-nano-structure film have been studied by measuring the transient change after excitation by a femtosecond laser pulse. The measurements indicate that the elec
