“…However, for 1047 nm oscillation, the thermal population distribution at laser wavelength is weak comparing that at 1030 nm, therefore, the central wavelength shift of 1047 nm is smaller than that 1030 nm oscillation even though the intracavity intensity is higher. The central emitting wavelength shift observed in Yb:LuAG microchip lasers are in good agreement with those observed in Yb:Y 2 O 3 [50] and Yb:YAG [51] ceramic lasers.…”

The performance of laser-diode end-pumped Yb:LuAG microchip lasers has been investigated at ambient temperature without active cooling of the gain media. Efficient laser oscillation of Yb:LuAG crystals with different thickness and output couplings was achieved at 1030 and 1047 nm with slope efficiencies of 72 and 54%, correspondingly. The thermal population distribution at the terminated laser level of Yb:LuAG crystal plays an important role in the laser performance. The effects of the thickness of Yb:LuAG crystal and the transmission of output couplers on the laser oscillating wavelength and central wavelength shift were investigated by taking account into the reabsorption loss at lasing wavelength and intracavity laser intensity.

“…Although many excellent experiments have been obtained in Yb:YAG crystals [8][9][10][11], Yb:YAG ceramic has been proved to be potential replacements for single crystals because of their remarkable advantages [12][13][14][15]. Compared with single crystals, ceramic can be fabricated into a large size with lower cost.…”

“…Comparative investigation of laser performance of Yb:YAG ceramics and crystals has been done and results show that Yb:YAG ceramics provide comparable or better laser performance comparing to their counterpart Yb:YAG crystals doped with different Yb concentrations [34]. Efficient laser performance of heavy doped Yb:YAG ceramics has been demonstrated recently [35,36]. High power laser-diode pumped Yb:YAG lasers based on Yb:YAG ceramics and crystals have been demonstrated with different laser resonator configuration such as thin disk lasers [37][38][39][40], rod lasers [41], microchip lasers [33,42], and slab lasers [43].…”

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
