“…upconversion loss. 4,5 Most importantly, its intense and broad absorption band near 940 nm makes it highly suitable for InGaAs diode pumping. Recent years, diode-pumped high power CW laser, 6 passively Q-switched laser, 7 passively mode-locked and femtosecond laser have been reported with polycrystalline Yb:Y 2 O 3 ceramic, 8 and the highest slope efficient of CW laser in Yb:Y 2 O 3 ceramic has reached 82.4%.…”

“…Due to high quantum efficiency of the 1048 nm transition line, the thermal load can be substantially reduced compared to that of the Nd:YAG lasers. Because the doping concentration of Yb 3+ can exceed 50 %, the optimal crystal thickness for diode end pumping can be fairly shortened to below a few 100 µm, which is beneficial for thin disk type or monolithic lasers [6,7]. Due to relatively broad gain bandwidth, mode locking operations for ultrashort pulse lasers are also reported [8,9].…”

Operation properties, such as output power, beam radius, and crystal temperature rise were investigated in a diode-pumped edge-cooled monolithic Yb:YAG laser with ~ 4 W pumping level. The output power showed saturation behavior because of severe temperature rise and poor spatial overlapping between pump beam and lasing mode. Face cooling geometry by using a sapphire plate was also investigated. No apparent saturation behavior in output power was observed due to the reduced temperature rise, which could be attributed to efficient heat removal through the crystal-sapphire interface.

By exciting at 940 nm, we have characterized the 1.84 m near infrared emission of trivalent thulium ions in Yb 3+ , Tm 3+ :KGd͑WO 4 ͒ 2 single crystals as a function of the dopant concentration and temperature, from 10 K to room temperature. An overall 3 H 6 Stark splitting of ϳ470 cm −1 for the Tm 3+ ions in the Yb 3+ , Tm 3+ :KGd͑WO 4 ͒ 2 was obtained. We also studied the blue emission at 476 nm ͑Tm 3+ ͒ and the near infrared emissions at 1.48 m ͑Tm 3+ ͒ and 1 m ͑Yb 3+ ͒ as a function of the dopant concentration. Experimental decay times of the 1 G 4 , 3 H 4 , and 3 F 4 ͑Tm 3+ ͒ and 2 F 5/2 ͑Yb 3+ ͒ excited states have been measured as a function of Yb 3+ and Tm 3+ ion concentrations. For the 3 F 4 → 3 H 6 transition of Tm 3+ ions, we used the reciprocity method to calculate the maximum emission cross section of 3.07ϫ 10 −20 cm 2 at 1.84 m for the polarization parallel to the N m principal optical direction.
