A nationwide real estate corporation is considering adding a new service line to sell the house of a client that buys another house through one of their agencies. It has determined that the first cost would be $80 million cash available for full implementation. However, John, the corporate vice president of sales, is not sure how well the service will be received, so he has projected added revenues using optimistic, most likely, and pessimistic estimates of $35 million, $25 million, and $10 million, respectively, with equal probability for each. Instead of expanding now, the company could implement a pilot program for 1 year in a limited geographic area that will cost $4 million now. (The full-scale service will still cost $80 million if implemented later.) This will provide the
company with the option to move forward or cancel the project. The criterion identified to move ahead with full-scale implementation is that added revenues during the pilot program must exceed $900,000. In this case, the pessimistic estimate will be eliminated, and equal probability placed on the remaining revenue projections. If the company uses a 5-year planning horizon and a MARR of 12% per year, should the company go ahead with the full-scale service now or take the option to implement the pilot program for 1 year?

A laser operates on the fundamental principle that a pumped medium amplifies a travelling light beam as it propagates through the medium. Without mirrors a laser becomes a single-pass travelling wave amplifier (Figure E.26.1).
This is a system without feedback. If we now place mirrors at each end of the pumped medium, we introduce feedback into the system.
When the gain of the medium becomes large enough the system oscillates creating a coherent output light beam. That is laser operation. If the gain of the medium is less that that required to sustain oscillation, the system is known as a regenerative travelling-wave amplifier (RTWA).
Let the electric field of a light beam incident on the RTWA from the left be the excitation of the system, Einc(s), and let the electric fields of the reflected light, Erefl (s), and the transmitted light,
Etrans (s), be the responses of the system (Figure E.26.3).
