Time-resolved photoelectron emission microscopy and spectroscopy
Based on the success story of our White Dwarf OPCPA with high performance operation at a single wavelength, we now also provide tunable solutions for demanding spectroscopy and microscopy applications.

Ultrashort pulses (< 30 fs) are delivered in a spectral range from 650 to 1300 nm. This makes the White Dwarf WD-800-tunable the most flexible non-colinear OPA on the market.
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 White Dwarf OPCPA technology to bring industrial performance to scientific output parameters.

This White Dwarf OPCPA version offers ultrashort pulses below 30 fs over a large tuning range and even can be offered as gap-less version with tunability from 650 to 1300 nm without spectral gaps.

Example sytem White Dwarf with integrated Coherent Monaco.
Normalized spectral intensity over tuning range 250-1700 nm: Pump laser Coherent Monaco 60 W, 1 MHz repetition rate, White Dwarf OPCPA WD-800-tunable with NIR and IR-extension plus SHG and THG.
The White Dwarf WD-800-tunable can be tuned gap-less from 650-1300 nm in a single OPCPA module. This allows SHG and THG from 250-650 nm, thus giving access to the whole range from UV to NIR.
Long-term power stability measured with powermeter (averaged shots) over more than 50 hours: Pump laser Coherent Monaco 60 W, 2 MHz repetition rate, White Dwarf OPCPA WD, 4.2 W average power and 0.4 % standard deviation.
