YVO₄ crystals separately doped with Er³⁺ and together with Er³⁺,Yb³⁺ radiate at 1.54, 1.61 mm wavelength and are used in eye-safe lasers. In contradiction to glass doped with Er³⁺,Yb³⁺ YVO₄ crystals can perform in cw regime with high pumping power and high efficiency. Their thermal conductivity is several times higher than thermal conductivity of glass that leads to improvement of generation characteristic of laser and lowers requirements to heat sink.

    YVO₄:Yb³⁺ has absorption broad band at 0.98 mm and can generate at @1.02 mm with high efficiency in connection with low loss of transfer  of pumping energy. “Solix Co. Ltd.” Grows the following crystals: YVO₄:Er³⁺, YVO₄:Yb³⁺, YVO₄:Er³⁺,Yb³⁺.
