In Stavropol, scientists have created a new material that increases the efficiency of lasers by suppressing parasitic radiation. The development was carried out by specialists from the North Caucasus Federal University (NCFU) and is already being considered for use in industry, medicine, and cosmetology.
Researchers clarify that laser systems lose some power due to unwanted oscillations within the active medium. The new material acts as a "filter" that cuts off these interferences and stabilizes the radiation, making the laser's operation more precise and energy-efficient.
The development is based on yttrium-aluminum garnet with added samarium, further modified with scandium. Scientists have established that the concentration of scandium critically affects the material's ability to absorb parasitic radiation and increase the stability of the laser process.
According to the developers, the material can be used in neodymium lasers of various powers – from industrial installations for metal cutting and welding to medical devices and cosmetology systems.
In the future, the team plans to scale the technology and create large-sized laser elements for implementation in industrial equipment.
