Source: MDPI The Twisted-Mode Technique in Laser Technology Understanding Spatial Hole Burning and Gain Saturation In continuous-wave lasers with linear resonators, a standing-wave interference pattern in the laser gain medium leads to spatial hole burning. This phenomenon causes stronger gain saturation for the lasing resonator mode compared to other modes, making single-frequency operation challenging unless
