“…Previously, 1.4 µm laser transition is a branch of 4 F 3/2 → 4 I 13/2 for Nd 3+ which is affected by crystal fields such as garnets, rare-earth aluminates, double rare-earth tungstates, and rare-earth oxides [3,5,11,12]. Nd:LuGdAG (Nd:Lu 2.9 Gd 0.1 Al 5 O 12 ) is a new garnet crystal which manifests manifold transition spectra lines [13]. High efficient mode locking and Q-switching oscillation have been obtained by Nd:LuGdAG for 1.06 [14] and 0.9 µm [15], respectively.…”

An LD pumped Nd:LuGdAG (Nd:Lu2.9Gd0.1Al5O12) eye-safe laser is reported in this paper for the first time. Using a plano-concave resonator, maximum continuous wave output powers of 1.00 and 1.05 W were obtained under an absorbed pump power of 8.52 W for T = 2%–3% and 5%–7%, corresponding to an optical to optical conversion efficiency of 12.3% and 11.7% and a slope efficiency of 14.5% and 13.6%. With five to seven layers of graphene saturable absorber, passively Q-switched 1444 nm operation was achieved for the first time. The maximum average output power found was 0.29 W with 324 ns as the shortest pulse width and a highest repetition rate of 64 kHz.

“…Lu 2.9 Gd 0.1 Al 5 O 12 (LuGdAG) crystal also belongs to the rare-earth garnet family (space group O 10 h -Ia3d). For Nd:LuGdAG crystal, the high absorption cross section of 3.52 × 10 −20 cm 2 at 809 nm, high stimulated emission cross section of 4.36 × 10 −19 cm 2 at 1063.5 nm and long fluorescence lifetime of 262 µs for the 4 F 3/2 level make this crystal one of the most attractive laser hosts for achieving ultrashort pulse duration [21].…”

Passive mode locking of Nd:Lu 2.9 Gd 0.1 Al 5 O 12 (Nd:LuGdAG) crystal lasers was experimentally investigated. Stable mode-locked pulses with pulse widths as short as 9.7 ps were obtained for the Nd:LuGdAG crystal; the corresponding maximum output powers were 0.93 W while the mode-locked slope efficiencies were 43%, among the highest efficiencies ever reported for Nd 3+ ps lasers. The results demonstrate that Nd:LuGdAG garnet crystal is a promising gain medium for efficient picosecond laser use.
