Concept explainers
To explain: Whether a laser can put out more energy than is put in or not.
Answer to Problem 16A
No, the laser cannot put out more energy than is put in.
Explanation of Solution
Introduction:
Laser can be explained as light amplification by stimulated emission of
Laser cannot be considered as a source of energy but it is a converter of energy. The given statement does not require more knowledge about lasers as it is based on the law of conservation of energy. So, a laser cannot put out more energy than is put in because then the law of conservation of energy will be violated. Energy must be conserved.
Conclusion:
Hence, the laser cannot put out more energy than is put in.
