Blackbody Spectrum & Lasers SIM Homework - PhET

(called the “threshold”) suddenly laser light comes out and as you increase above that theamount of laser light produced increases rapidly. This behavior can be observed in the PhETlaser applet as well as in any real laser. Explain this behavior of a threshold for laseroperation in terms of the underlying physics of lasers.d) (1 pt) Lasers are used in all sorts of modern technology. What characteristics of laser lightmake it special and especially useful in technology (try to give examples of where thisfeature is made use of in your everyday life)? In your description of the characteristics,explain why the physics of how lasers work produce these characteristics.
