Sapphire, garnet and vanadate crystals are the most prominent optical materials, and vanadates play important roles in optics, especially in lasers and nonlinear optics. Neodymium‐doped yttrium vanadate (Nd:YVO4) is representative and available commercially. Based on Nd:YVO4, several vanadate crystals are being developed with the goal of fulfilling the need for differential applications and improvement of certain operational aspects, such as with pulsed lasers or high‐power continuous‐wave lasers. In recent years, some important effects, including energy enhancement, bistability of output performance, self‐Raman frequency shifting, etc., and some novel applications, such as quantum optics, pulsed lasers modulated by the two‐dimensional crystals, etc., have been discovered with vanadates as gain materials. In this paper, the preparation, characterization and laser applications of vanadate laser crystals at the lasing wavelength of 1 micrometer, including YVO4, GdVO4, LuVO4, GdxY1–xVO4 and LuxGd1–xVO4 (0 < x < 1) doped with Nd3+ and ytterbium (Yb3+) are systematically reviewed by highlighting the most recent research progress. Their specific properties are presented, generation mechanisms of novel physical effects are discussed, new applications are given and possible future applications proposed by focusing on some potential strengths.

“…Traditionally, the Nd 3+ ions are pumped into the highly absorbing 4 F 5/2 level by diode laser around 808 nm. Successful attempts to lase the Nd 3+ doped laser at 1.3 µm have been reported [3][4][5][6][7][8][9][10][11]. However, the 808 nm pumping would introduce a large quantum defect of around 40% between the pump and lasing wavelength operating at 1.3 µm, which resulted in low efficiency and high heat deposition.…”

We describe the output performances of the 1.35 μm 4 F 3/2 → 4 I 13/2 transition in Nd-doped Sr3Ga2Ge4O14 (SGG) under in-band pumping with diode lasers at the 879 nm wavelength, directly into the 4 F 3/2 emitting level. An end-pumped Nd:SGG crystal yielded 7.1 W of continuous-wave (CW) output power for 17.7 W of absorbed pump power. The slope efficiency with respect to the absorbed pump power was 47.7%. To the best of our knowledge this is the first demonstration of such a laser system. Comparative results obtained for the pump with diode laser at 806 nm, into the highly-absorbing 4 F 5/2 level, are given in order to prove the advantages of the in-band pumping. Output power at 1.35 μm versus the absorbed pump power
