Chinese research team has developed an advanced imaging technique to achieve super-resolution microscopy at unprecedented speeds and with many fewer images. The new method should make it possible to capture processes in living cells at speeds not ...2019-12-13
High power continuous-wave (CW) single frequency 780 nm lasers with excellent beam quality have received significant attentions for the growing important role in atomic physics and quantum optics. Narrow linewidth, frequency stable 780 nm laser c...2019-12-12
Real-time and fast measurements in adaptive optics are becoming urgent in order to meet the real time requirement of high-power laser, astronomical observations and optical communication.2019-12-10
Ghost imaging (GI) is a novel imaging technique based on the correlation of light intensity fluctuations. In recent years, it has attracted a lot of interests owing to its high detection sensitivity, non-local imaging property and the ability to a...2019-11-28
White light laser, which is also common known as supercontinuum (SC), is encountering a great quantity of applications in recent years. The SC characterizes both good beam quality and broadband wavelength coverage. Provided that the SC emits a hig...2019-11-26
In 2008, Nishiura et al. reported that the Ce:YAG transparent ceramics are suitable for white LED. Since then, the investigation of Ce:YAG transparent ceramics have been broadly studied. However, the PL spectra of Ce:YAG transparent ceramics lacks...2019-11-21
Fluoride crystals can be ideal optical and photonic materials due to their low phonon energy, high transmittance in wide wavelength range and high solubility of rare earth ions. However, they can hardly realize large-scale and complex shapes in pr...2019-11-18
Ultrashort laser pulses featuring remarkable spectral tunability are highly demanded for investigating basic physical and chemical properties in the ultrafast dynamic processes, which are based on time-resolved spectroscopy (also called ultrafast ...2019-11-14
Imaging through scattering media is an ever-lasting topic in wide fields from biomedical to atmospheric optics. Comparing to other prevailing methods, speckle autocorrelation imaging stands out because it is simple, fast and non-invasive. Its prer...2019-11-13
Perovskite materials have excellent optical properties, such as large carrier mobility, long diffusion length, large absorption coefficient and high quantum efficiency, which not only have excellent performance in the field of photovoltaics, but a...2019-11-12
