Experimental data of the high-energy, high-beam-quality, and widely tunable laser system

Figure 2 Data: The theoretical tuning curve of KTA crystal is calculated by Sellmeier equation, and the experimental measurement wavelength is measured by spectrometer (YOKOGAWA, AQ6370D) Figure 3 Data: Pump energy and signal light energy tests were measured by an energy meter (COHERENT, USB J-50MT-10KHZ) Figure 4 Data: The beam quality was measured by a CCD camera (Xenics, XEVA 13552 XEN-000168), and the energy meter was the same as above Figure 6 Data: Energy and wavelength tests as above, spectrum as above The testing equipment for Figures 7, 8, and 9 is the same as above
