1) - measured with Avesta's AA-10DD-12PS interferometric autocorrelator using Gaussian fitting; motorized tunable pulse duration with PC control up to 10 ps is also installed by default; the Compulse-1030 external hollow-fiber pulse compressor with output pulse duration down to 30 fs is also available as an option;
2) - external second, third and fourth harmonic generators are available upon request; certain built-in combinations are also available; Raman shifters to 1530 nm and 1890 nm are also available;
3) - measured under stable environmental conditions;
4) - measured at maximum average power and 100 kHz repetition rate.
