Source: MDPI The Importance of Finesse in Optical Resonators Understanding Finesse in Optical Resonators Finesse is a critical parameter that measures how narrow the resonances are in an optical resonator in relation to their frequency distance. It is defined as the free spectral range divided by the bandwidth of the resonances. A high finesse indicates […]

Source: Instagram Understanding Free Spectral Range in Optical Resonators The Concept of Free Spectral Range in Optical Resonators The free spectral range of an optical resonator, also known as the axial mode spacing, refers to the frequency spacing between its axial resonator modes. This parameter plays a crucial role in the performance of optical resonators.

Source: Semantic Scholar The Science Behind Active Mode Locking in Lasers Active mode locking is a technique used in lasers to generate ultrashort pulses by modulating the resonator losses or round-trip phase change. This method involves using devices such as acousto-optic or electro-optic modulators to achieve synchronization with the resonator round trips, resulting in the
