3. where we have assumed that (AP/P) i s proportional to the specific energy deposition, E. We have also assumed that the prototype laser has the same dimensions as the test device in the plane perpendicular t o the optical path so that Ap = At. A typical prototype design i s based upon an energy deposition of 90 J/a-atm, a pressure of Pp = 10 atm, and an optical length of Lp = ,93 cm. The constants describing the refractive index are oP = 45.9 x 10-6 and E t = 59.7 x 10-6. Using these numbers in Eq. (10) we obtain cP = 16.5Nct where N is the number of passes the laser beam makes through the cavity during the laser pulse. For N = 2, 33ct. From Fig. 16, the strength o f the re;fected wave i s approximately e t = * 5 "rad. Therefore, a similar reflected wave i n the prototype w i l l result in a deflection
