Laser properties of Yb(3+)-doped Sr5(PO4)3F crystals
Abstract
Yb(3+) based lasers have received substantial attention over the past several years. Yb-based materials, which typically lase around 1 micron, are aided by the simple electronic structure of Yb(3+) in that it has only two accessible electronic states eliminating the detrimental impact of upconversion or excited state absorption. In addition, the inherently small quantum defect of approximately 10-15% has led to relatively large intrinsic laser slope efficiencies. The pumping and extraction dynamics of Yb:Sr5(PO4)3F crystals will be discussed. A diode array and a free running Cr:LiSAF laser are utilized as pump sources for both Yb-oscillators and amplifiers.
