[0019] Ce doped with YAG crystal 3+ Taking the spin detection of ions as an example, under the action of a continuous laser with a wavelength of 473nm, electrons will obtain a transition from the ground state 4f energy level to the excited state 5d energy level. figure 1 It is a specific device for detecting the transient process of electron spin. The 473nm laser is generated by a diode-pumped low-noise solid-state continuous laser. The continuous laser source obtains periodically and continuously switched left-handed and right-handed circularly polarized light through a polarizer, an electro-optic modulator and a 1 / 4 wave plate; the fluorescence detection window is set at 528-537nm, and the light is collected through a convex lens, and the filter The excitation light is filtered out, the fluorescence enters the avalanche photodiode through a 1 / 4 wave plate and an analyzer, and the signal finally enters the digital oscilloscope for detection.
