Abstract :
Crystals of Cr4+ doped yttrium aluminum garnet (YAG) have been used as a solid state, saturable absorber Q-switch for 1064 nm. Research has been conducted on its spectroscopic properties, including ground state and excited state absorption cross sections (σgs and σes). However, the reported values of σgs and σes vary more than an order of magnitude. We conducted Z-scan measurement of σgs and σes in Cr4+:YAG at 1064 nm to provide useful data for use in modeling the performance of passively Q-switched lasers
