Montgomery, Harris CorporationThe transcript opens during a discussionof internally scanned lasers, shortlyafter the start of the session.V. FOWLER: When you internally scan alaser, you inevitably wind up with adevice that has somewhat less powercapability and efficiency than withexternal modulation, some loss of co-herence and some loss of resolvingpower or spatial coherence. The bestway to design a system with technologythat is available today is in building -block fashion: get a good laser, pre-serve its spatial coherence, get a goodmodulator, do a good job at hanging thepieces together so the resolution ispreserved throughout the system; inother words, hang the system on thiscoherent beam. It's not necessarilythe only way to go. I think that inthe future if we come up with a singledevice that serves multiple functions,it would be nice to get around the costof that modulator, for example.
