Integration of alumina-phosphate glass with cobalt-doped magnesium aluminate structure using a hot embossing technique for microlaser development.

In this work, the technique of hot embossing has been applied for the bonding of alumina-phosphate (PAL) glass with cobalt-doped magnesium aluminate (MALO) crystals. The application of the hot embossing technique for bonding of PAL/MALO is a competitive method, as compared to the existing thermobonding techniques. The obtained PAL/MALO interfaces show high quality, similar to what is currently achievable with other, more expensive traditional methods.
