  • Hot YAG:Yb3+:Er3+ crystal-a potential laser medium for high average power 1.5 μm lasers
  • 2006
  • Ingår i: Advanced solid-state photonics 2006. - : Optical Society of America. - 1557527989 - 9781557527981
  • Konferensbidrag (refereegranskat)abstract
    • The near-IR spectroscopic properties of YAG:Yb:Er crystals were investigated at high temperatures. It is shown that at 600°-800°C temperatures they become close to their corresponding properties in Er,Yb: phosphate laser glasses.

  • New crystalline material for 1.5 μm lasers : Yb,Er - Activated GdCa 4O(BO3)3
  • 2004
  • Ingår i: Advanced Solid-State Photonics. - Washington, D.C. : Optics Info Base, Optical Society of America. - 1557527717 ; , s. 430-434
  • Konferensbidrag (refereegranskat)abstract
    • A new crystalline medium for 1.5 μm Yb-Er lasers is proposed: GdCa 4O(BO3)3 (GdCOB). Its melting point allows crystal growth using platinum instead of iridium crucibles. Spectroscopic and laser tests of the new material are described. A maximum CW output power of 80 mW was achieved in a monolithic microchip cavity under laser diode pumping.

  • Yb3+,Er3+:YAG at high temperatures : energy transfer and spectroscopic properties
  • 2007
  • Ingår i: Optics Communications. - : Elsevier BV. - 0030-4018 .- 1873-0310. ; 271:1, s. 142-147
  • Tidskriftsartikel (refereegranskat)abstract
    • Energy transfer and spectroscopic properties at high temperatures have been investigated in Er,Yb:YAG crystals. It is shown that at elevated temperatures around 600-800 degrees C these characteristics become similar to those in the efficient 1.5 mu m laser medium - Er,Yb-doped phosphate glasses.

  • Laser performance of Yb : GdCa4O(BO3)(3) compared to Yb : KGd(WO4)(2) under diode-bar pumping
  • 2007
  • Ingår i: Laser physics. - : Pleiades Publishing Ltd. - 1054-660X .- 1555-6611. ; 17:10, s. 1204-1208
  • Tidskriftsartikel (refereegranskat)abstract
    • A study of Yb:GdCOB under diode-bar pumping has been performed and the results are compared, experimentally and theoretically, with Yb:KGW in the same cavity. An output power of 7.3 W and a slope efficiency of 57.4% were obtained. Self-frequency-doubling experiments are also discussed.
