Abstract
A high-quality Nd0.01:Gd0.89La0.1NbO4 (Nd:GLNO) crystal is grown by the Czochralski method, demonstrating wide absorption and fluorescence spectra and advantage for producing ultrafast laser pulses. In this paper, the tunable and passively mode-locking Nd:GLNO lasers are characterized for the first time. The tuning coverage is 34.87 nm ranging from 1058.05 to 1092.92 nm with a maximum output power of 4.6 W at 1065.29 nm. A stable continuous-wave (CW) passively mode-locking Nd:GLNO laser is achieved at 1065.26 nm, delivering a pulse width of 9.1 ps and a maximum CW mode-locking output power of 0.27 W.

Summary
Ultrafast lasers have been applied in various fields, such as high-precision micro machining, aerospace, and medical diagnostics [1,2]. Benefiting from their low quantum defects, wide gain bandwidth, and simple three-level electronic structure, Yb3+ -doped laser mediums attract widespread attention in the 1 μm band [3,4,5]. Compared with Yb3+ -doped gain mediums, Nd3+ -doped crystals have no reabsorption loss and are used in low-threshold and high-efficiency ultrafast laser. 0.80 nm, respectively [6,7] For this reason, considerable efforts have been made to explore novel Nd3+ -doped laser materials with a broad gain bandwidth.
