Managing thermal effects in high-power solid-state lasers
The performance and power levels from solid-state laser have escalated dramatically in recent years, primarily associated with increasing efficiency and brightness of diode-laser pump sources. This has led to a similar increase in the thermal load within the solid-state gain medium itself, a by-product of the excitation cycle, which has had to be managed appropriately to continue to achieve increasing output powers. Choosing the right gain media, its geometry, and the cooling method have all been critical parameters in this complex interplay between light and heat. In this presentation, we will discuss the recent progress in solid-state laser performance; the role fibre lasers have played and make comparisons with other laser architectures. Of particular interest to this forum is the thermal management constraints and where we are in terms of fundamental limits for these systems. It will be demonstrated that we are indeed very close to the limits already, where novel approaches and engineered materials will be paramount for future power scaling potential.

Abstract

The performance and power levels from solid-state laser have escalated dramatically in recent years, primarily associated with increasing efficiency and brightness of diode-laser pump sources. This has led to a similar increase in the thermal load within the solid-state gain medium itself, a by-product of the excitation cycle, which has had to be managed appropriately to continue to achieve increasing output powers. Choosing the right gain media, its geometry, and the cooling method have all been critical parameters in this complex interplay between light and heat. In this presentation, we will discuss the recent progress in solid-state laser performance; the role fibre lasers have played and make comparisons with other laser architectures. Of particular interest to this forum is the thermal management constraints and where we are in terms of fundamental limits for these systems. It will be demonstrated that we are indeed very close to the limits already, where novel approaches and engineered materials will be paramount for future power scaling potential.
