APE’s Levante Emerald picosecond OPO is now available with sufficiently high signal output power to provide tunable picosecond pulses in the <195-215nm ultraviolet range.
More than 5mW average power is available at 207nm with a spectral bandwidth of less than 0.1nm. Distributed in the UK and Ireland by Photonic Solutions, the standard Levante Emerald OPO offers widely tunable picosecond pulses of >0.75W in the 690–990nm (signal) and >0.6W in the 1150-2300nm (Idler) ranges at 80MHz repetition-rate. This new Levante Emerald HP comes with increased signal output power of over 6W and, when coupled with APE’s HarmoniXX FHG frequency conversion unit, offers computer-controlled tuning between 190nm and 215nm, and with >5mW at 207nm. The HarmoniXX unit may be configured to provide higher power, tunable picosecond pulses at longer wavelengths up to around 325nm. This new light source sees applications in ultrafast spectroscopy and pump-probe measurements in the UV range, photo-electron spectroscopy and direct one-photon excitation of UV transitions.
