“…Recently, the effect of radiation trapping has been widely inves tigated for Yb 3+ doped laser materials and various methods have been proposed to limit it [4,[14][15][16]. In this work, in order to reduce the effect of radiation trapping, the powder method [14] is adopted to measure the fluorescence decay curves of Yb 3+ :Ca 3 La 2 (BO 3 ) 4 crystal.…”

“…Highly efficient intracavity frequency-doubled Yb:YAG lasers have been demonstrated recently [17][18][19][20]. Highly efficient laser performance of Yb:YAG at 1048 nm under 968 nm laser-diode pumping has been also demonstrated [21], and efficient continuous wave (CW) frequency doubling of Yb:YAG laser under 968 nm pumping has also been demonstrated [22]. Frequency doubling of Yb:YAG lasers at 515 nm matches the highest power line of Ar-ion lasers, thereby leading to the possibility of an all solidstate replacement [23].…”

Enhancement of laser-diode pumped self-Qswitched Cr, Ca, and Yb 3+ ions co-doped YAG (Cr,Yb:YAG) lasers by bonding Yb:YAG ceramic to increase pump power absorption efficiency have been demonstrated for the first time to our best knowledge. Efficient Cr,Yb:YAG self-Q-switched laser performance has been achieved by bonding Yb:YAG ceramic. The effect of transmission of output coupler (T OC ) on the laser performance has been investigated and found that the best laser performance was achieved with TOC = 20% for Yb:YAG ceramic. Slope efficiency of 20% was achieved with T OC = 20% for Cr,Yb:YAG self-Q-switched laser by bonding Yb:YAG ceramic. Maximum average output power of 683 mW was measured at absorbed pump power of 4.5 W; the corresponding optical-to-optical efficiency is 15.2%. The output laser pulse characteristics were compared for Cr,Yb:YAG self-Q-switched lasers by bonding Yb:YAG ceramic and crystal under different transmission of output coupler. For the same T OC , the laser performance of Cr,Yb:YAG self-Q-switched lasers by bonding Yb:YAG ceramic is better than that by bonding Yb:YAG crystal. T oc = 10%, η s = 13% T oc = 20%, η s = 20% T oc = 30%, η s = 16% Yb:YAG crystal:T oc = 10%, η s = 5% T oc = 20%, η s = 14% T oc = 30%, η s = 18%Average output power of Cr,Yb:YAG self-Q-switched lasers by bonding Yb:YAG ceramic and crystal as a function of the absorbed pump power for different transmission of output coupler, TOC

“…Transitions from the energy level 2 F 5/2 to 2 F 7/2 of Yb:YAG lead to laser operation at 1048, 1030, 1024 and 968 nm. Quite recently, a diode-end-pumped Yb:YAG dual-wavelength cw laser at 1048 and 1030 nm has been reported [54]. To the best of our knowledge, no research on quasi-three-level dual-wavelength operation at 1024 µm and 1030 nm in Yb:YAG lasers has been reported.…”

A diode-end-pumped Yb:YAG dual-wavelength continuous-wave (cw) laser that generates simultaneous laser action at wavelengths of 1024 and 1030 nm is demonstrated for the first time. A total output power of 897 mW for the dual-wavelength was achieved at an incident pump power of 17.8 W. Furthermore, intracavity sum-frequency mixing at 1024 and 1030 nm was then realized in an LBO crystal to reach the green range. We obtained a total cw output power of 85 mW at 513.5 nm.
