Gain-switched electrically pumped VECSEL for picosecond pulse generation at 1030 nm

Researchers at FBH and LZH demonstrate picosecond pulse generation from a novel gain-switched electrically pumped VECSEL. The concept enables operation in the low-MHz regime without intracavity components and paves the way for compact sources targeting LiDAR, sensing, and seeding applications.
The image shows a precisely constructed photonic module in a gold-colored housing. It contains several components, including wires, lenses, and circuit boards. A ruler is visible in the background to illustrate the scale of the technical details.
