“…Since the 1990s, laser-diode-pumped slab lasers have been the study focus in the world, which are considered as one of the most efficient approaches to generate the lasers with high output powers and high beam qualities [1][2][3][4]. In the recent years, based on the traditional slab lasers, the researchers have developed some novel slab lasers [5][6][7]. A corner-pumped type is a new diode-pumped type for slab lasers, which was first presented by our research group [7,8].…”

A corner-pumped type is a new pumping type in the diode-pumped solid-state lasers, which has the advantages of high pump efficiency and favorable pump uniformity. A corner-pumped Nd:YAG/YAG composite slab continuous-wave 1319 nm/1338 nm dual-wavelength laser is first demonstrated in this paper. When the cavity length is 25 mm, the maximal output power is up to 7.62 W with a slope efficiency of 16.6% and an optical-to-optical conversion efficiency of 17%. The corresponding spectral line widths of 1319 nm laser and 1338 nm laser are 0.11 and 0.1 nm, respectively. The short-term instability of the output power is better than 1% when the pumping power is 39.5 W. The experimental results show that a corner-pumped type is a kind of feasible schedules in the design of diode-pumped solid-state 1.3 μm lasers with low or medium output powers.
