Absorption of Excited State of Cr4+∶YAG Crystal
Cr4+∶YAG is studied as a saturable absorber of 1064 nm laser. The dynamic process of excited state absorption (ESA) is described by using rate equations, with the crystal interacting with low or high power laser. The function about intensity varying with the transmission derived by rate equations is demonstrated by experiment. Therefore, it is shown that the Q switching is possible and can be optimized by using the ESA of the crystal.
