The present invention relates to a solid-state laser comprising: a) a
semiconductor pump laser, b) a lens integrated on the surface of said
semiconductor pump laser, c) a packaging material consisting essentially
of a spin-on glass material, wherein the spin-on glass material is
processable at a process temperature of less than 225.degree. C., and d)
a lasing material layer having a highly reflective coating in both sides.
The invention also relates to a process for producing such a solid-state
laser, which process comprises applying spin-on glass material onto
semiconductor wafers having VCSEL pump lasers using different coating
methods, such as spin coating, and curing the glass film layer at
temperatures <225.degree. C.; printing desired patterning of the
material by contact or proximity lithography methods and forming
diffractive lens structures to shape the pump laser radiation into the
lasing material which constitutes spin-on glass material doped with rare
earth elements, such as erbium (Er) and ytterbium (Yb), or with
semiconductor nano-particles or quantum dots.
