Photodynamic therapy (PDT) has poor therapeutic outcomes for the treatment of port-wine stain (PWS) lesions with long drug-light intervals (DLIs). This letter investigates the possibility of improving the treatment efficacy through increasing the laser po
A 16*10-Gb/s optical time-division-multiplexing (OTDM) system was demonstrated experimentally with a well-designed ultrashort pulse source based on an electro-absorption modulator (EAM) and nonlinear fiber compressor. The obtained 10-GHz stable and pedest
The nonlinear Talbot effect is a near-field nonlinear diffraction phenomenon in which the self-imaging of periodic objects is formed by the second harmonics of the incident laser beam. We demonstrate the first, to the best of our knowledge, example of non
