White Dwarf Attodriver

OPCPAs for XUV attosecond pulse generation

Few-cycle pulses at 800 or 2000 nm
Average power > 12 W
CEP stable < 150 mrad

Introduction

Compact few-cycle laser for attosecond pulse generation

The White Dwarf Attodriver is designed for attosecond science and efficient XUV generation enabled by carrier-envelope phase (CEP) stable few-cycle pulses on a compact footprint.

On a compact footprint of less than < 1 m² our one-box solution integrates an industrial pump laser with a high-performance few-cycle CEP-stable OPCPA. With two available wavlengths 800 nm or 2000 nm you can target either the EUV or soft-X-ray water window spectral region for your unique attosecond light source.

FAQ

Which wavelength options are available for the Attodriver OPCPA?

The product is available with few-cycle pulses at 800 nm or 2000 nm, respectively

How does passive CEP work?

The Attodriver generates intrinsically CEP stable pulses by generating a difference frequency generation (DFG) that is subsequently amplified

Does the Attodriver OPCPA also come with active CEP feedback?

Depending on the model, active CEP feedback is included or optionally available. It allows to correct for slow CEP drifts, for example, due to temperature changes in the laboratory.

Why is the Attodriver OPCPA so stable?

Our advanced engineering integrates compact design and efficient thermal management to ensure maximum stability and reliability at highest average powers.

What pump laser included in the Attodriver OPCPA?

We package the Attodriver with newest generation Yb:YAG industrial lasers from 80 – 200 W average power.

How can I generate EUV or soft-X-rays with the Attodriver OPCPA?

The generation of extreme ultraviolet (EUV) or soft-X-ray pulses can be achieved via high-harmonic generation (HHG), for example in our Moonlander HHG. While the 800 nm version of the Attodriver OPCPA enables 20 – 100 eV HHG photon energies, higher photon energies up to the water window can be achieved using the 2000 nm version.
