GATE Physics PYQs 2012–2025 | Atomic & Molecular Physics : Lasers | POTENTIALG | Lalit Sir

#potentialg In this video, Lalit Sir solves and explains GATE Physics PYQs (2012–2025) from the topic Atomic and Molecular Physics, with special focus on Lasers and Spectroscopy. This lecture covers both theory + numerical PYQs and is extremely useful for GATE Physics, CSIR NET, JEST, TIFR, and M.Sc / Ph.D entrance preparation. 📚 Topics Covered: Spectra of one- and many-electron atoms Spin-orbit interaction LS and jj coupling schemes Fine and hyperfine structures Zeeman and Stark effects Electric dipole transitions & selection rules Rotational and vibrational spectra of diatomic molecules Electronic transitions & Franck–Condon principle Raman effect EPR, NMR, ESR spectroscopy X-ray spectra Lasers: Einstein coefficients, population inversion, two- and three-level laser systems All explanations are concept-based, exam-oriented, and fully aligned with GATE Physics PYQs (2012–2025). 👉 This session is part of the Atomic & Molecular Physics series on POTENTIALG by Lalit Sir.
