3D Printed Micro-Optics Revolutionize Hybrid Laser Stability

Researchers have successfully 3D printed micro-optics onto optical fibers, creating a stable hybrid laser that combines the advantages of fiber-based and crystal-based solid-state lasers. The 3D-printed lenses exhibited high damage threshold and stability, allowing the laser to operate at output powers of over 20 mW. This breakthrough enables the development of inexpensive, compact, and stable laser sources that have potential applications in lidar systems for autonomous vehicles, lithography, laser marking, and medical procedures such as precise tissue destruction. The researchers are now working on optimizing the efficiency of the printed optics and exploring different crystals for customized laser outputs.
