The idea of exploiting glass transformation normally associated with thermal heating and quenching by using localized laser processing for various applications has been demonstrated in recent times through the bulk thermal annealing of laser patterned glass. Low temperature stable laser-induced bond breaking, density and stress changes within an optical fibre have since been stabilized to temperatures in excess of 1200°C through the process of regeneration. We review this process in light of recent results.
