Pulse Shapers

Source: National Institute of Standards and Technology Understanding Pulse Shaping in Photonics Introduction Pulse shaping is a crucial technique in the field of photonics, especially when dealing with ultrashort pulses in the picosecond or femtosecond range. These pulses are typically generated using specialized lasers and require precise manipulation of their temporal and spectral characteristics for […]

Group Delay

Source: YouTube The Concept of Group Delay in Optics Group delay is a fundamental concept in optics that describes the time delay experienced by a light pulse as it propagates through an optical element. The group delay is typically dependent on the optical frequency or wavelength of the light. It is defined as the derivative
