Pr3 +-Yb3 +‐codoped lanthanum fluorozirconate glasses and waveguides for visible laser emission

► We fabricated Pr3 +-Yb3 +‐codoped fluoride glass waveguides by PVD. ► The blue, green, orange and red luminescence of Pr3 + was studied by direct and indirect pumping schemas. ► The up-converted luminescence is similar in bulk and waveguide upon excitation at 980 nm.
