Tm:YVO_4 microchip laser

Abstract: When pumped with a 1-W laser diode, a Tm:YVO(4) microchip laser produced 150 mW of 1.92-µm output in a near-diffraction-limited beam at room temperature. Using a Ti:Al(2)O(3) laser to pump the same device, we showed that reducing the temperature of the Tm:YVO(4) from 20 to -30 °C resulted in no measurable change in threshold and increased the slope efficiency by only 20%.

“…Additionally, the 3 H 4 multiplet of Tm 3+ ion can be directly excited by the welldeveloped AlGaAs laser diodes around 800 nm. Therefore, more and more attention has been focused on the design and fabrication of various Tm 3+ doped crystals, such as the aluminates YAG [7], YAP [8]; the fluorides LiYF 4 [9], LiLuF 4 [10]; the vanadates YVO 4 [11], GdVO 4 [12], and so on. Among these crystals, Tm:YAG is considered as one of the most excellent laser crystals to generate high power laser emission around 2 μm.…”

“…Recently, an attention was paid to the development of 2 µm-microchip lasers, because of their simplicity, compactness and possibility to achieve the single longitudinal mode operation. Tm-or Tm,Ho-microchip lasers based on YVO 4 [5], GdVO 4 [6], YLiF 4 [7,8] or YAlO 3 [9,10] laser host materials have been realized.…”

“…Although there are some reports on the investigation of optical properties of Yb:YVO 4 [2,6e10], there is no systematic evaluation of absorption and emission characteristic as a function of doping concentration over the wide solubility range of Yb in YVO 4 . Further there are some ambiguities on the effect of doping concentration on the lattice parameter.…”
