1. Introduction
1.1. Purpose
This Requirements Specification Document (RSD) lists the technical requirements and
constraints for the optical parametric amplifiers (OPA) for the ELI Beamlines facility (ELI).
These instruments shall have the ability to convert pulses generated by L1 laser system
(central wavelength ~850 nm, ~20fs) and pulse from the alignment lasers (central
wavelength ~805 nm, ~35fs) into comparably short pulses of other wavelengths, in order
to cover an entire regime from near UV to mid-IR (0.2-20 µm). Optimization of OPA
systems to the unconventional pulse characteristics of L1 laser (OPCPA) are to be provided.
The OPAs are outlined by the following main parts:
- Parametric light generation unit
- Further mixing units (higher harmonic, sum frequency, and difference generation units)
to extend the tuning range beyond parametric generation.
- Covered box console allowing change wavelength remotely by PC, and easily change
mixing regimes without change in pointing and timing
- beam splitting and beam size converting optical assembly to distribute beams into OPA,
ideally in configuration with tunable splitting ratios
- Software to control the instruments including graphical user interface
- the expected configuration is in three independently operational OPA units (each may be
one or multi box solution):
1) for high energy conversion (HE-OPA) (pump~8mJ) from 850 nm to ~260-2600
nm
2) for medium power conversion (ME-OPA) (pump ~2mJ) from 805 nm to ~1902600 nm
3) for medium power conversion to mid infrared (IR-OPA) (pump ~2mJ) from 805
nm to ~2600-20000 nm
1.2. Scope
This RSD contains all of the top level functional, performance, safety, operational, design
and quality requirements for the RA4 system in experimental hall number 1 (E1). In
addition to the requirements specified in this RSD, this system shall comply completely
with the requirements given in the “FZU Specifikace” document and in the ELI-Beamlines
Summary of User Requirements Specification.
