We present a novel approach for measuring the differential static scalar polarizability of a target ion utilizing a "polarizability scale" scheme with a reference ion co-trapped in a linear Paul trap. The differential static scalar polarizability of the target ion can be precisely extracted by measuring the ratio of the ac Stark shifts induced by an add-on infrared laser shed on both ions. This method circumvents the need for the calibration of the intensity of the add-on laser, which is usually the bottleneck for measurements of the polarizability of trapped ions.

Article Synopsis
- - The study investigates how supercontinuum generation occurs in photonic crystal fiber when exposed to femtosecond laser pulses, using a Ti:sapphire optical amplifier as the pump source.
- - By analyzing spectrograms under varying power and wavelength conditions, researchers observed that increasing pump pulse power broadens the spectral width and introduces additional peaks, eventually stabilizing at high intensities.
- - The experiment concluded that at a fixed pump power of 300 milliwatts and fiber length of 105 millimeters, the wavelength of the pump pulse significantly influences the width and shape of the supercontinuum, especially within the 760 to 840 nm range.
