Basic Laser Technique Laboratory
The goal of the practicum is to get the basic practical skills in laser physics and to learn to work independently on a given problem, to formulate the task and to present the results.
In academic year 2023/2024 the laboratory will be scheduled in Trojanova 13, Praha 2, CTU campus, lab Tn228, Tuesday 14:00, summer semester. The complete task schedule was specified after the first meeting and it is published in Czech version of this page only. In academic year 2023/2024 foreign student are in group "D" and "E" as listed there. The yellow color in the table is a confirmation of protocol acceptance.
The internal code of this course is 12ZPLT. Students are evaluated by graded assessment with value of 6 credits.
Old English versions of task instructions are in general valid even for current academic year, but topical details kindly consult with the assistant.
General laser safety precautions
- Use appropriate protective glasses.
- Open laser output shutter for necessary time only.
- Never use the eye as a laser beam detector; use visualizers plate, a camera, or a photodetector.
- Always terminate the laser beam optical path, either by beam stop (black plate) or a photodetector. The optical path should be straight, horizontal, and as short as possible.
Task list:
- Free-running and Q-switched Nd:YAG laser, laser amplifier and second harmonic generation
- Diode pumped Nd:YAG laser
- He-Ne laser glow discharge properties
- TEA CO2 laser parameters and marking application
- Spectral characteristics of optical components
- Nonlinear transmission of saturable absorbers
- The measurement of a transverse profile of laser beam by Knife Edge method
- Acousto-optical modulator with traveling and standing acoustic wave
Rules for academic year 2023/2024:
- One group – one protocol, no waste words, required results only.
- Protocol has to be sent electronically to email address in footer in 1 week after measurement with code 12ZPLT in subject line, i. e. before next measurement. No protocol – no access to lab.
- The preparation will be tested in beggining, unprepared student will be rejected (to the spare time slot).
- The clasification is individual based on protocols and overall activities in lab. The clasification record will be done by dr. Blažej.
- For classification discussion kindly save your own laboratory log (in electronic or paper form).
