We report the first experimental observation, to the best of our knowledge, of soliton molecules in a robust all polarization-maintaining (PM) mode-locked fiber laser with a nonreciprocal phase bias that results in a low self-starting threshold and stable mode locking.Through elaborately tuning the waveplate in the cavity, calibrating the laser pul
Low-cost device for active saliva droplet filtration and pathogen inactivation
This work presents a device capable of performing sanitization in environments using an electrostatic filter and ultraviolet light.Recognized techniques were employed in an innovative and low-cost construction model, where to buy opi nail polish toronto like Corona Discharge and UVC germicidal light, using elements of easy acquisition and construct
