A team of researchers has developed a novel method for using cholesteric liquid crystals in optical microcavities. The ...

The Mamyshev oscillator (MO) is a type of fiber laser capable of producing high-energy laser pulses at a tunable repetition ...

Physicists at the University of Oxford have unveiled a “pioneering” method for capturing the full structure of ultra-intense ...

A novel widely tunable laser diode is proposed and demonstrated. Mode selection occurs by etching perturbing slots into the laser ridge. A two-section device is realized with different slot patterns ...

By insertion of two intracavity solid Fabry-Perot etalons into a traveling-wave dye ring laser an instrumental line width of 0.1 pm was attained in single-mode operation. Using different dye solutions ...
