Technology

Unilase technology is based on side-pumped slab designs that offer a natural route for power scaling laser and amplifier output by providing independent control over pump delivery, cavity geometry and thermal management. Such flexibility allows for robust and compact designs with very high overall efficiency. Unilase Ltd is not encumbered by prior art IP and all arising IP from projects commissioned by customers belongs to the customer in their field of commercial exploitation.
