Laser technology illustrates many modern applications that require exact measurements and communication. Scientists, led by NTNU’s Johan Reminsburger, have developed a new integrated laser that is fast, powerful, relatively cheap and easy to use. The work is in collaboration with Switzerland’s Acol Polytechnic Fuderial de Lozon (EPFL) and Chip Specialist Localins. This approach removes the key limits of traditional precision lasers, which are usually large, expensive and difficult to adjust. According to Reminsburger, such lasers can enable small, cheap, high -performance equipment and communication systems.
Advanced material, microscope circuits
According to research published in Nature Photonics, the new laser is implemented using advanced materials such as thin film lithium neabite, which takes advantage of its electro -optic (poke) effect for ultra -fest, mood -free frequency toning. It connects the lithium nebat circuit with a commercial semiconductor Gain chip, which gives a laser, which is both powerful and strong.
It emits a stable beam and allows the frequency to adjust quickly and easily without a mood hips. Specifically, the device can be operated using the same tuning knob instead of numerous controls. Since it depends on the standard chip fabric process, the laser can be widely manufactured. “It is possible to produce small, cheap and user -friendly equipment and communication tools with high performance,” says Reminsburger.
Self -run cars and air quality detectors
Traditional health lasers are often big, expensive and tuning difficult. “Our new laser solves many of these problems,” Reminsburger has noted. The team demonstrated the device in the lord (light detection and ranging) system of self -run cars, where laser reflective measurements measure the distance through pulses. The laser acquired about the precision of about four centimeters, which enabled a lot of resolution environmental mapping.
Its rapid, mood -free tuning allows it to sweep the gas absorption lines, which enables trace hydrogen to detect sensitive detection, which demonstrates rapid gas sensing capacity in safety and environmental monitoring. In fact, EPFL’s Simon Bayakoni notes that the combination of laser synchronization, low noise output combination makes it integrated leather and precision gas sensing app suitable.
