a 1176 nm laser output power at various cooling temperatures (upper panel) and without cooling (lower panel). b Thermal-field distribution inside laser crystal, where the highest value denotes crystal temperature. c Crystal temperature-dependent 1176 nm laser output power at a fixed pump power 7.7 W. d, e 2D lasing phase diagram and general threshold relation Pth×Tth = C. The dots are measured results. Experimental data in Fig. 5d are presented as mean values±SD with five samples.
