Abstract
Diamond Raman lasers are an emerging high-power laser technology offering kW-level beam powers with high brightness. Here we report experimental observation of a diamond thermal lens at output powers up to 1.1 kW in a quasi-steady-state regime. It is found that a thermal lens of up 16 diopters is induced, which causes the beam quality to evolve over the investigated power range. The results aid design at higher power and clarify conditions under which beam quality degradation is expected when scaling output power.
