Lasers have widespread applications as a light source in a variety of fields, including manufacturing, medicine, high-speed communications, electronics, and scientific research.

Through this strategy, they achieved a wide tunable range from 481 ps to 1.38 ns. This almost 1 ns tuning range is the largest ever reported for a narrow-bandwidth passively mode-locked laser.

Narrow-bandwidth mode-locked lasers have potential benefits in many fields, including diamond cutting and semiconductor manufacturing. However, currently they have fixed, rigid pulse duration ...

In a recent study, published in Advanced Photonics Nexus , researchers presented an innovative ultranarrow bandwidth mode-locked laser with a tunable pulse bandwidth. "We have successfully developed ...

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 ...
