Study Notes
LASER Characteristics
- Stimulated emission is the process by which a photon stimulates the emission of another photon.
- NOT a characteristic of LASER: (question left open, assume it's a multiple-choice question)
LASER Definition
- LASER stands for Light Amplification by Stimulated Emission of Radiation.
Photon Energy Calculation
- The energy of the photons emitted by a transition between energy levels E2 and E1 is calculated based on the wavelength of the emitted light, in this case, 632.8 nanometers.
- The energy of the emitted photons can be calculated using the energy levels involved in the transition.
Lasing Action and Energy Levels
- Lasing action can take place between energy levels, such as from E3 to E2, emitting light of a specific wavelength, in this case, 1.4 micrometers.
- Energy levels can be calculated relative to a reference level, in this case, E1 and E2 are at 0 eV and 1.4 eV respectively, and E3 can be calculated using the energy difference between the levels.
