Room-temperature diode-pumped Yb:YAG laser

Abstract: We have developed an efficient room-temperature ytterbium-doped YAG laser operating at 1.03 microm pumped by an InGaAs strained-layer diode laser operating at 968 nm. The threshold was 234 mW and 23 mW of output power was obtained for an absorbed pump power of 345 mW. This laser offers a number of advantages over AlGaAs pumped Nd:YAG lasers, such as broader absorption features, longer fluorescent lifetime, and lower thermal loading of the gain medium.

“…Rare earth ions, from Ce 3+ to Yb 3+ , possess especial electronic structure and abundant energy levels, so relatively strong MD transition is not difficult to find. In Yb 3+ , the 4f 13 electron configuration has only two energy-level manifolds, the ground state 2 F 7/2 and an excited state 2 F 5/2 , which are separated by about 10600 cm −1 [27]. According to selection rules, MD transition is allowed between them.…”

“…Yb:YAG crystals have been widely studied because they have various advantages for efficient diode-pumped lasers [1][2][3][4]. Yb:YAG has a broad pump line at 940 nm that is 10 times broader than the 808 nm pump line in the conventional Nd:YAG, which makes the system less sensitive to thermal drift of the laser diode (LD) wavelength [5].…”

“…Recent development of InGaAs laser diode has stimulated interest in Yb 3+ -doped solid-state materials used as gain for high-efficiency, high-power diode-pumped solid-state lasers [1] . Among the numerous Yb-doped crystals, Yb : Y 3 Al 5 O 12 (Yb : YAG) is the most promising laser-active medium due to small quantum defect (8.6%), no excited state absorption and up-conversion, large absorption and emission width, long fluorescent lifetime, and excellent physical and chemical properties.…”
