Optical laser

Optical laser pulses, which are matched with and synchronized to the FEL pulse train are provided for time-resolved pump-probe experiments.

 

The pump-prope laser developed at European XFEL

The laser group at European XFEL has developed a pump-probe laser, which is based on non-collinear optical parametric amplification (NOPA). Currently available parameters are listed below.

 

wavelength pulse duration repetition rate pulse energy
800 nm 15 fs 1.1 MHz 0.25 mJ
800 nm 15 fs 200 kHz 1.3 mJ
800 nm 15 fs 100 kHz 1.8 mJ
1030 nm 900 fs 1.1 MHz 3 mJ
1030 nm 400 ps 1.1 MHz 3 mJ

 

Optical setups for 2nd and 3rd harmonic generation are also available. Do not hesitate to contact Patrik or Daniel for more information and suggestions!

 

A fiber-based laser amplifier

In addition, a second commercial laser system is available at SQS with the following parameters:

 

repetition rate wavelength pulse duration pulse energy
1.1 MHz 1030 nm < 300 fs 0.2 mJ
0.5 MHz 1030 nm < 300 fs 0.4 mJ
0.1 MHz 1030 nm < 300 fs 2.0 mJ
0.1 MHz 1030 nm < 40 fs 1.0 mJ
