The impact of thermal effects on filamentation and supercontinuum generation in bulk materials at MHz pulse repetition rates
Abstract We experimentally study the impact of beam focusing geometry-related heat accumulation on supercontinuum spectra in YAG crystal pumped with 210 fs, 1030 nm pulses by varying pulse repetition rate in the 200 kHz - 2 MHz range. It is demonstrated that in the case of converging pump beam, the...
