A single mode laser is a laser that emits light in a single spatial and spectral mode, producing a narrow, high-intensity beam with low divergence.
Researchers at the University of Shanghai for Science and Technology have developed a neural network assisted laser frequency locking system that uses predicted values to reduce nonlinearity.
External cavity diode lasers (ECDLs) are a type of laser that use a diode as the light-emitting element. These lasers are characterized by their high efficiency and low cost, making them popular for many applications including telecommunications, spectroscopy, and laser printing.
