Abstract:
|
One can become almost incoherent trying to remember how we taught physics without the laser. In April 1963 the first issue of The Physics Teacher appeared, and the journal soon began to carry seductive advertisements for lasers showing how the physics teacher could use this wonderful new device in the lecture room and the laboratory. Two years later the Kenyon College physics department paid $1,650 for a relatively short-lived laser, and I was hooked. In this talk I will use advertisements from TPT to show how the prices decreased and our expertise in using the laser increased. Soon it became as indispensible to teaching physics as a multimeter or a meter stick.

Abstract:
|
Laser safety is not always given the attention it might warrant. When one evaluates the level of laser safety required, using a laser pointer is substantially different than aligning a Class 4 laser. This presentation will emphasize basic laser safety when using Class 3B or Class 4 lasers in a university setting but could easily be applied to any similar facility or classroom environment. Laser safety information presented and practices described will be in accordance with the American National Standard for Safe Use of Lasers (ANSI Z136.1 - 2007) and CLSOs' Best Practices in Laser Safety (Laser Institute of America - 2008).
