Abstract

We present our first results on the coherent combination of four rod type Thulium doped fiber amplifiers. With this we achieved a pulse energy of 1.34 mJ and an average output power of 130 W at a repetition rate of 98 kHz with a compressed pulse duration of 123 fs. This system represents the highest output power mJ class laser system in the SWIR to date and proves the average power and pulse energy scaling capabilities of ultrafast Tm doped fiber amplifiers.
