Programmable and tunable flat-top supercontinuum laser sources via electro-optic intensity and phase modulation scheme.

In this study, we presented flat-topped coherent supercontinuum lasers with tunable repetition rates and programmable spectral bandwidths. Supercontinuum sources with ultra-broadband and high-repetition-rate coverage can be achieved by merging nonlinearly broadened electro-optic optical frequency combs with optical line-by-line spectrum shaping. Spectral bandwidth programming is implemented by iterative spectrum shaping and input power control of highly nonlinear stages, whereas repetition rate tuning is performed by modulation speed control in optical frequency combs.

Structured nonsurgical Asian rhinoplasty.

The Asian nose is characterized by a flat nasal bridge, indistinct dorsal aesthetic line, an underprojected and broad nasal tip, and a short columella. Cosmetic procedures to enhance these features are popular in Asians and surgical rhinoplasty is the therapeutic gold standard for individuals seeking to enhance the appearance of their nose. However, in recent years, there appears to be an increasing number of Asians seeking nonsurgical rhinoplasty and this tendency is seen in both primary and revision cases.
