The T-Light is a robust and compact turn-key femtosecond fiber laser. It offers exceptional performance for a variety of applications, from ultrafast spectroscopy to THz physics. The laser design is based on polarization (PM) maintaining fiber components, which is the key to stable operation. Menlo Systems’ unique figure 9® mode locking technology ensures reproducible and long-term stable operation. The result is a reliable fiber laser source, designed for 24/7 operation.

Amplitude noise < 0.2% / °C peak to peak with temperature cycling from 15 to 35°C
