Solid-state laser for pumped light has laser-active material coated on a pumped light entry surface to reflect laser wavelengths and anti-reflect pumped wavelengths and vice versa on a facing side.

摘要

A lens (a) focuses pumped light into a laser crystal (c) with both a first coating (L) that is highly transmitting for pumped wavelengths and highly reflective for laser wavelengths and with a second coating (P) that is highly reflective for pumped wavelengths and highly transmitting for laser wavelengths. A pumping mirror (b) has an accentric hole. A decoupling mirror (d) acts for laser beams.
