Real-time observation of soliton build-up dynamics in a mode-locked laser
Recently, researchers at Zhejiang University demonstrate the first observation of the entire build-up process of solitons in a mode-locked laser, revealing two possible ways to generate the solitons. One way includes the dynamics of raised relaxation oscillation, quasi mode-locking stage, spectral beating behavior, and finally the stable single-soliton mode-locking. The other way contains, however, an extra transient bound-state stage before the final single-pulse mode-locking operation.
Noniterative spatially partially coherent diffractive imaging using pinhole array mask
Recently, researchers at Soochow University (SCU) and Delft University of Technology (TUD) demonstrated the reconstruction of a phase object under spatially partially coherent illumination using a pinhole array mask (PAM). This PAM is specially designed such that one can retrieve the correlation function of the incident light by inverse Fourier transforming the measured diffraction pattern.
