| 标题 | Light Emission and Lasers |
| 仿真程序 | 氢原子模型, 激光器 |
| 关键词 | absorption, emission, sponataneous absorption, stimulated emission, lifetime of states |
| 描述 | This in-class work (ICW) is used in a university non-math "How Things Work" course (replacing the lecture). It is designed to accompany section 14.3 in Bloomfield's text (3rd ed). It uses the "Models of the Hydrogen Atom" and "Lasers" simulations. Note: I really preferred the older edition of the Lasers simulation for this activity... if anyone has it, I'd love to get a copy! I liked the representation of IR photons better because they looked more "invisible", and I think the settings were nicer to get clear cases of spontaneous and stimulated emission effects as dependent on light intensity and state lifetime. Contact me for solutions (or if you have a copy of the old sim!). |
