Scientists Demonstrate Continuous Lasing Effects on Devices

A Group of Researchers has Demonstrated Continuous Lasing in Devices Produced from Perovskite Materials.

If you are familiar with Lead-halide perovskites, then you already know that the elements are considered some of the most promising materials for production of lasers in the future. Recently, a group of researchers from Tel Aviv University (TAU) and Karlsruhe Institute of Technology (KIT) has demonstrated continuous lasing action in devices made from perovskites.

During the course of the research, the group produced devices using nano imprinting technology that uses moderate temperature and pressure to shape different materials.

The study was first published on the journal Nature Communications. Talking about the recent demonstration, Professor Jacob Scheuer of TAU’s Department of Physical Electronics said, “In contrast to previous studies around the world, this is the first study to exhibit continuous lasing action, as opposed to pulsed operation. This family of materials is considered the most promising candidate for a future laser-based industry, because their fabrication is simple, fast and inexpensive compared to current semiconductor materials being used for these purposes.”

He added, “This is an important breakthrough in the field of novel solid-state lasers because it demonstrates the potential of the perovskites material system for continuous lasing in the visible spectrum. It proves that these materials ‘have what it takes’ to replace conventional semiconductor laser technology, paving the way for laser-based illumination, projectors, cellphone and laptop displays, etc. These displays can provide brighter and more vivid colors that can operate even under direct sunlight without necessitating more power consumption.”

“But for a practical system we need to improve the quality of the materials and structure so they can also work at room temperature and be powered by an electric power supply such as a regular battery. These are our next challenges.”
