Physics Internship: High-harmonic generation in gases


In a nutshell


Veldhoven, Netherlands


No experience (Student)



Job Category



Are you a master student with an educational background in Physics, preferably supervised from within an atomic or optical physics group? Do you have affinity towards optical experiments? Then this internship could be interesting for you!

Background information

Next-generation optical metrology tools for the semiconductor industry may require radiation in the soft x-ray regime (SXR, wavelength <20 nm) to resolve the ever-shrinking structure size in integrated circuits. In an ASML research project, we investigate the generation of SXR by means of high harmonic generation (HHG), in which intense laser pulses are fired into a gas target resulting in up conversion of the laser light to SXR wavelengths.

Your assignment

HHG SXR emission is the result of the laser field ionizing electrons and subsequently recolliding them with their parent atoms, their kinetic energy being released in the shape of high-energy SXR photons. The properties of the resulting SXR beam emitted by the gas target depend, amongst other things, on the details of the trajectories followed by the electrons between ionization and recollision. In this internship, you will work in a state-of-the-art ultrafast laser research lab, to experimentally demonstrate how generation process of the SXR beam can be controlled by applying various non-linear optical techniques. The goal of the internship is to studying the effects of laser pulse properties on the conversion efficiency and further enhance the understanding of HHG process.

Your profile

  • You are a master student with a background in Physics, preferably supervised from within an atomic or optical physics group;
  • You are a master student looking to do your graduation project or gain work experience;
  • You are experimentally oriented, with an interest in optical/atomic physics;
  • You have affinity towards optical experiments;
  • Students who attended courses on Electromagnetism are preferred;
  • You are available to do a full-time internship with a duration of 9-12 months.

Please note that we can only consider students who are enrolled at a school for the entire duration of the internship.

Other information

Change the world – one nanometer at a time
Become an intern at a Dutch company that’s a global industry leader. You’ll gain valuable experience in a highly innovative environment – one that sparks your imagination and creativity. In addition to a monthly internship allowance of maximum €500 (plus a possible housing or travel allowance), you’ll get practical guidance from experts in the field and the chance to work in and experience a dynamic team environment.

ASML: be part of progress
ASML is a high-tech company headquartered in the Netherlands. We manufacture the complex lithography machines that chipmakers use to produce integrated circuits, or computer chips. What we do is at the heart of all the electronic devices that keep us informed, entertained and connected. Every day, you use electronics that simply wouldn’t exist without our machines.

Behind ASML’s innovations are engineers who think ahead. The people who work at our company include some of the most creative minds in physics, electrical engineering, mathematics, chemistry, mechatronics, optics, mechanical engineering, and computer science and software engineering.

We believe we can always do better. We believe the winning idea can come from anyone. We love what we do – not because it’s easy, but because it’s hard.

Students: getting ready for real-world R&D
We’re a global team of about 29,000 people of 120 different nationalities and counting. Headquartered in Europe’s top tech hub, the Brainport Eindhoven region in the Netherlands, our operations are spread across Europe, Asia and the US.

In such an environment, your colleagues may be sitting next door, or they could be thousands of kilometers away in a different country – or even working for a different company.

An internship at ASML is the opportunity to get to know not only the world of industrial-strength R&D, but yourself – you’ll discover just what excites you most. Will you design a part of the machine, or make sure it gets built to the tightest possible specifications? Will you write software that drives the system to its best performance, or work side-by-side with the engineers of our customers in a fab, optimizing a system to the requirements of the customer?

How will you be part of progress?
