Report: Atomic and Molecular Spectra Laser by Rajkumar PDF 56

Processes:

• Atomic Spectra: One-electron systems, spin, fine structure, and hyperfine structure.
• Molecular Spectra: Rotational, vibrational, and electronic spectra, as well as Raman spectroscopy.
• Laser Physics: Basic principles, population inversion, Q-switching, and mode locking.

7. Example: Sodium D-Line – From Lamp to Laser

The sodium D-line (589.0 and 589.6 nm) originates from ( 3p \rightarrow 3s ) transition. With a low-pressure sodium lamp, the line is Doppler-broadened (( \sim 3 ) GHz at 500 K). With a tunable diode laser locked to the D-line, one can: Atomic And Molecular Spectra Laser By Rajkumar Pdf 56
