Source: link.springer.com Understanding Thermal Lensing in Laser Systems What is Thermal Lensing? Thermal lensing is a phenomenon that occurs in laser gain mediums when heat is generated during pumping. This heat leads to temperature gradients within the medium, causing changes in the refractive index and mechanical stress. These effects can result in a lensing effect

Source: Fosco Connect Understanding Gain Guiding in Laser Systems When a laser beam propagates in a medium, it naturally expands due to diffraction. To prevent this expansion, a guiding structure known as a waveguide is typically used, which has a spatially varying refractive index profile. Alternatively, gain guiding can be employed, where guiding is achieved
