Spectroscopic analysis and efficient diode-pumped 2.0 μm emission in Ho3+/Tm3+ codoped fluoride glass

- Intense 2.0 μm emission has been obtained in Ho3+/Tm3+ codoped ZBLAY glass.
- Radiative properties have been determined using Judd-Ofelt theory.
- Energy transfer is analyzed using Inokuti-Hirayama and Förster-Dexter models.
- Present glass possesses high emission cross section and quantum efficiency.
- This Ho3+/Tm3+ codoped ZBLAY glass is a promising material for 2.0 μm laser.
