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 […]
