Our White Dwarf OPCPA powered by Coherent has its pump laser already on board to enter the next level of stability. We integrate the Coherent Monaco industrial femtosecond laser on a small footprint with state-of-the-art OPCPA technology to bring industrial performance to scientific output parameters.

The White Dwarf OPCPA for few-cycle pulses is especially designed to provide high-power and extremly short pulses at a single wavelength: 800, 1550 or 2000 nm. Optionally, the system can be configured to provide passive CEP stability which is a great benefit for robustness, reliability and stability in phase dependent measurements. Additionally, an active feedback loop can be integrated to stabilize the CEP over slow drifts.

Example sytem White Dwarf with integrated Coherent Monaco.
Normalized spectral intensity: White Dwarf OPCPA WD-800, central wavelength ca. 800 nm, 4 W average power, 1 MHz repetition rate, Pump laser Coherent Monaco 40 W.
Long-term power stability measured with powermeter (averaged shots) over more than 14 hours: Pump laser Coherent Monaco 40 W, 1 MHz repetition rate, White Dwarf OPCPA WD-800, 4.2 W average power and 0.4 % standard deviation.
Retrieved temporal intensity profile measured via SHG-FROG: White Dwarf OPCPA WD-800, central wavelength ca. 800 nm, pulse duration FWHM 8.9 fs, 4 W average power, 1 MHz repetition rate, Pump laser Coherent Monaco 40 W.
Carrier-envelope phase (CEP) stability: Depicted is the average CEP per minute (red) and standard deviation per minute (rms, brown). If the stabilization is turned ON (active feedback loop) slow drifts in CEP are compensated. A total rms value of 174 mrad is achieved.
Pump laser Coherent Monaco 60 W, 1 MHz repetition rate, White Dwarf OPCPA WD-800, 1.2 W average power.
