Pulsed laser source L

picosecondultra-short pulsefiber

Product overview
The L series ultrashort‑pulse fiber laser delivers a broadband supercontinuum with pulse widths at the picosecond level. Repetition rate and output power are adjustable to meet different application requirements. An external trigger is available as an option. The manufacturer can also customize pulse width, repetition rate, output power, divergence angle and other optical parameters on request.
