Abstract
We report on a 300-W industrial femtosecond laser with ultrashort compressed pulses. Pulse compression is performed within a gas-filled multi-pass cell and results in about 50fs pulses at an energy of 600µJ. Long terms tests of more than 10 days revealed excellent long term and short-term stability of the system. Relevant laser and system parameters are continuously monitored and logged thus enabling to correlate these parameters with results obtained when using this laser for scientific experiments or machining applications. The perspectives to even shorter pulses and higher power and pulse energies will be discussed.
