Mode-locked laser operation of Indium-modified Yb:KY(WO_4)_2 single crystal

Abstract

We report the first pulsed laser operation of an Indium-modified Yb:KY(WO4)2 crystal. Indium incorporation enlarges the broadening of the Yb3+ optical bands, reduces crystal lattice parameters and increases n(p) refractive index. A KY0.8In0.07Yb0.13(WO4)2 crystal pumped at 981 nm with a Ti-sapphire laser in a SESAM modulated resonator produces at 300 K self-starting and stable mode-locking. The shortest laser pulses achieved were centred at λ = 1041.1 nm, have a duration of 96 fs with average power of 134 mW and repetition rate of 103.5 MHz (1.3 nJ/pulse).

“…monoclinic Yb:KLn(WO 4 ) 2 lasers. 63 Undoped CNGG-type crystals can be grown with a microscopic crystallographic quality as good as that of commercial YAG crystals, see Fig. 2b.…”

Laser floating zone growth of Yb, or Nd, doped (Lu0.3Gd0.7)2SiO5 oxyorthosilicate single-crystal rods with efficient laser performance

“…More details about the laser resonator and optical procedures can be found in a previous work. [44] In order to determine the absorbed pump power the Fresnel sample reflection was estimated using an average refractive index n= 1.8, accordingly with the values reported in previous literature for isostructural LSO. [25,45,46] Laser powers were measured with Gentec photodetectors, model UP19K-15S-H5D0.…”

Tunable luminescence and temperature sensing behavior of Tb3+/Eu3+ co-doped borate glasses

“…ions doped optical materials for their potential applications in solid-state lighting, laser, plasma display panels (PDP) and non-invasive temperature sensors [1][2][3][4][5]. However, the host materials, where RE 3? ions reside, should be strict selected due to that the radiative/ nonradiative energy transfer of RE 3? ions are highly dependent on the environment surrounding them [6].…”
