Subpicosecond pulse generation from a chirped-pulse multipass-cavity Cr4+:Forsterite oscillator

摘要

We produced the highest pulse energy directly generated from a room-temperature, mode-locked Cr4+:forsterite oscillator. The chirped-pulse, multipass-cavity, 1261-nm oscillator operated at 4.9 MHz and produced 81-nJ pulses which could be externally compressed to 620 fs.
