DIADEM
COMPACT HIGH-ENERGY FEMTOSECOND LASER
< 400 fs / Up to 40 µJ / Up to 30 W / 1030 nm and 1064 nm
DIADEM is a high-energy, versatile femtosecond fiber laser operating at either 1030 or 1064 nm in the most compact and robust air-cooled configuration on the market. DIADEM produces pulses of < 400 fs up to 40 µJ with many pulse control features such as adjustable pulse duration, selectable repetition rate from 40 MHz down to single pulse, or fine pulse energy tuning so that pulses can be emitted in various modes (on demand via external signal, burst of pulses with configurable pulse separation). DIADEM can also be equipped with an external computer-controlled frequency doubling module which offers on-the-fly wavelength selection at 1030 nm or in the green or UV wavelengths
