- Estimated study time: 30 minutes
Study resources
- The Science of Light Amplification - BARC and IIT Bombay (Article) — An extensive laser course run jointly by BARC and IIT Bombay. Optional depth, but the applications sections give strong real-world Indian examples.
- An Introduction to Lasers and Laser Systems - HBNI (Article) — Covers specific laser systems in detail, which is where He-Ne is treated properly. Most general courses rush this and it is a standard exam question.
- Laser: Fundamentals and Applications - IIT Kanpur (Article) — The closest single match for Unit 3. Week 2 is stimulated emission and Einstein's coefficients, Week 4 is three- and four-level lasers plus coherence and monochromaticity, Week 6 is applications.
- Introduction to Laser - NPTEL (Article) — A more mathematical treatment. Week 1 derives the Einstein A and B coefficients and their relations, Week 3 gives the condition for amplification, Week 4 does the two-, three- and four-level rate equ…
