Scientists from Novosibirsk State University (NSU) and Skolkovo Institute of Science and Technology have developed a fiber laser that can be adjusted independently without human intervention. This trainable laser can be applied in various fields such as metalworking, mechanical engineering, communications and medicine. The training process of this laser took only one day after automation and pre-training.
A fiber laser using an ion cell made of carbon nanotubes has been created by researchers at the Nanomaterials Laboratory of the Skolkovo Institute. They found that applying voltage to this cell allowed the properties of the absorber to be controlled, which increased their ability to control the laser. Scientists from NSU developed an algorithm that teaches the system to control the laser independently, including adjusting harmonic mode locking modes.
This new laser gives the system more freedom in tuning and can even achieve higher levels of harmonic synchronization than can be achieved by humans. Such fiber lasers could provide a more efficient and automated solution for generating short pulses and greatly expand their applicability in various fields.
