The Fritz Haber Institute of the Max Planck Institute in Berlin has achieved a technological milestone. The infrared free electron laser operates in dual color mode for the first time. This globally unique technology makes it possible to conduct experiments on synchronous dual color laser pulses, opening up new possibilities for research.There are over a dozen free electron lasers worldwide, with ...
The pump source, gain material, and resonant cavity are the three elements that make up a laser. Due to the selective effect of the resonant cavity on the lasing frequency, multi longitudinal mode operation is one of the characteristics of fiber lasers based on traditional resonant cavity structures, manifested as periodic beat peaks in the radio frequency (RF) spectrum and periodic fluctuations i...
Ultra short laser pulses for local welding (Source: Fraunhofer IOF)With the accelerated evolution of electronic devices towards high power, high frequency, and miniaturization, ceramic substrates have become core materials in fields such as power semiconductors, 5G communications, and new energy vehicles due to their excellent thermal conductivity, insulation, and high temperature resistance. H...
