I'm currently a bachelor's student in physics and work alongside my studies in a research group. I originally joined because I had some hands-on experience with maintaining vacuum systems and over time my work has grown to include writing code for instrument control, doing data analysis, and designing / building hardware.
Through this work, I've had the chance to learn a lot about ultrafast laser physics, mostly by being directly involved with the experiments and talking to the people doing their research.
In my free time, I enjoy repairing broken lab equipment, writing small software for fun and reverse engineering hardware to understand how it works.

I'll cover the fundamentals of laser operation, including gain, population inversion and how you convince a bunch of excited atoms to all emit light in sync instead of doing their own thing.
We then explore how femtosecond pulses are produced in practice.
I'll explain some simple methods for shaping, tweaking, and measuring those pulses.
As a practical example, I will walk you through the velocity map imaging (VMI) setup I work with to show what can be done with this equipment, watching molecules fall apart, like a molecular stroboscope.
