WebWe report a dysprosium-doped gain switched fluoride fiber laser pumped at 1064 nm and emitting at 3244 nm. Pulses with energies up to 1 µJ were generated on a wide range of repetition rates between 100 kHz and 200 kHz, the highest reported for a pulsed dysprosium-doped fiber laser, producing an average output power reaching 207 mW. WebSep 1, 2024 · The experimental configuration of all-fiber short pulse gain switched RFL is shown in Fig. 1. The pump source is a 1550 nm electrically modulated DFB laser. It possesses variable pulse repetition rate of 1.0–3.0 MHz and pulse duration of 1–10 ns. This pump laser is coupled into a linear Raman laser cavity through a 1550/1650 nm WDM. solace coffee beaverton
