Abstract

A diode-pumped Q-switched Tm3+-doped double-clad silica fiber laser is reported providing average powers of up to 30W at pulse widths of only 41ns and repetition rates in the range of 10125kHz. Up to 270μJ pulse energy was produced. Amplified spontaneous emission (ASE) buildup limits the maximum peak power, and the pump power and average output power at the point of ASE induced clamping were found to depend linearly on the repetition rate.
