Fiber Oscillator Extends Femtosecond Lasing into the Visible Band
SIMING, China, April 3, 2024 — Femtosecond (fs) fiber oscillators are a standard technology used to generate fs laser pulses. They offer a compact design, outstanding performance, and are cost-effective to use. However, the operating wavelengths for these oscillators are located primarily in the infrared (IR) region. Extending their reach to the visible (VIS) range, so they can be used in a variety of applications that require VIS light sources, has been a longstanding goal of laser science. In an advancement for
