Laser Experiments For Beginners [PDF ebook] 

The perfect blueprint for science teachers who want to bring one of the most remarkable research tools of the 20th century into their classrooms: the laser. Requiring only a low-cost, low-power laser (easily available for under $100) the book presents a series of experiments for in-class demonstrations or student activities. Quick-reference instructions identify needed equipment, recommend safety practices, and help select desired experiments. The book is designed to enhance existing courses in chemistry, physics, and biology.
