“…[6] When T oc becomes 1% and 3%, the lasing threshold increases to 2.63 and 3.89 W. And the maximum output power improves to 1.68 and 3.95 W, corresponding to a high slope efficiency of 34.1% and 52.4%, respectively. This slope efficiency at fluorescence sidebands even surpasses some non-vibronic Nd 3þ -doped laser at 1123 nm, [20,21] indicating the great potential of vibronic lasers despite its low-gain emission. Figure 2c displays the laser spectrum under various output couplers.…”

Electron–phonon‐coupling effect can generate the direct lasing beyond the fluorescence spectrum of the gain medium, but the laser efficiency is still low owing to weak multiphonon‐coupling intensity. Herein, associated with the three‐phonon‐assisted electron transitions beyond 1100 nm, the tunable laser generation from 1125 to 1155 nm and highly efficient continuous‐wave lasers at 1131 and 1140 nm in a ytterbium‐doped YCa4O(BO3)3 crystal are realized, by balancing the intracavity loss and phonon‐determined gain. The maximum output power reaches to 3.95 and 2.06 W at 1131 and 1140 nm, corresponding to a slope efficiency of 52.4% and 39.1%, respectively, which represents the highest efficiency in the solid‐state lasers in this spectral range. More impressively, this phonon‐assisted vibronic laser exhibits a wide‐spectral tunability and a good output power stability. Herein, a practical laser source in the underdeveloped spectral range is provided by the results, and they are helpful for the development of multiphonon‐assisted lasers beyond the inherent fluorescence spectrum.

“…Zang [5] et al developed a single frequency 1.25 W 1123 nm laser for stable coherent light sources study. S.S. Zhang et al [6,7] demonstrated diode-end-pumped continuous wave (CW) 1123 nm lasers both for ceramic Nd:YAG and composite Nd:YAG, the output power was 10.8 W and 9.3 W, respectively. Till now, there is no report on the output power of over 100 W for the CW operation of diode-pumped 1123 nm laser.…”

“…It is easy for side pumped Nd:YAG to achieve high power 1064 nm laser, but the o o efficiency in TEM 00 mode operation is relatively low, typically between 10% and 15% [8][9][10][11][12]. In comparison, end pumping can reach higher o o efficiency in TEM 00 mode oper ation.…”

We report an 885 nm laser diode (LD) end pumped high beam quality ( = 1.322, = 1.235) electro optical Q switched Nd:YAG laser with TEM 00 mode output for the first time. At the absorbed pump power of 59.5 W, a 22.7 W 1064 nm laser was achieved at 10 kHz repetition rate with optical to optical effi ciency of 38.1%. The maximum pulse energy and shortest pulse width were 5.1 mJ and 14.5 ns at 2 kHz rep etition rate, and the calculated peak power was 352 kW.
