Stabiλaser 1542ε – Acetylene‑Stabilized Fiber Laser

The Stabiλaser 1542ε (epsilon version) is a second-generation acetylenestabilized fiber laser. It offers the same narrow linewidth, excellent long-term stability, and high precision as its predecessor. The design retains the short-term linewidth of a high-end fiber laser while adding the longterm stability and accuracy derived from acetylene molecular transitions. As a high-performance laser source, it operates continuously and troublefree without user intervention. By combining the Stabiλaser 1542ε with an all-fiber frequency-doubling technique, an additional output at 771 nm can be obtained. This solution ensures that the 771 nm signal inherits the excellent short-term linewidth and long-term stability of the Stabiλaser 1542. The Stabiλaser 1542ε can deliver 1 mW of power at both 771 nm and 1542 nm. This solution can later be used to upgrade the Stabiλaser 1542ε.
