Nanosensorics lab training

(Mr. Mohamed Abdel-Awwad, M.Sc.)

Theory:
Laser operation conditions, theory of light-matter interaction and optical gain of the semiconductor materials..

Experiment:
Characterization of optical gain and losses in semiconductor materials.

Laser safety instruction

Goals

• Understanding absorption, spontaneous emission and stimulated emission in a semiconductor laser
• Optical gain and losses measuring using the Variable stripe length Method
• Safe handling of sophisticated optical setups with high power laser devices

What you will gain from the practicum

• You will learn the fundamentals of how light is created in a semiconductor laser.
• Performance of optical pumping experiments.
• Safe handling of sophisticated optical setups with high power laser devices.
• Valuable documentation of the results.
• Team-based working experience in a modern research environment.

General information

The student team is supervised by Mr. Abdel-Awwad, who is responsible for the coordination of the practicum for all participating students. The working schedule for the experiment is flexible.

Course prerequisite

The students of the B.Sc. Physik course, B.Sc. Nanostrukturwissenschaften course and M.Sc. Electrical Communication and Engineering course, have to attend the lecture ‚Nanosensorics‘.
