The Use of Lasers
*

The Damnation of Faust
by Terry Helbing
For the spring production of its twentieth anniversary season, the 0 pera Com pany of Boston presented the Boston
stage premiere of Hector Berlioz's The Damnation of Faust. In
keeping with the premiere spirit, and given her long history of
bringing innovation to the Boston opera scene, Artistic Director Sarah Caldwell decided to use lasers to create "supernatural effects" for the opera. S he felt the Faust story would
particularly lend itself to this unusual interpretation.
Caldwell contacted David Infante, founding president of
Laser-Physics, Ltd., a New York-based company that "specializes in research and development of lasers and laser
applications for industry and theatre." Infante's previous laser
projects have included effects for several rock and disco
groups, the World's Biggest Discotheque Tour, which began
at Madison Square Garden, and a Star Wars laser concert
with the American Symphony Orchestra at the Minskoff
Theatre in New York. Caldwell contracted Infante for the
opera after seeing two demonstrations of the laser's capabilities at Laser-Physics' laboratory/showroom.
The laser used for the production was an argon/krypton
gas laser. These lasers range in power from 1 to 20 watts;
electrical requirements range from 115 volts, 1 phase, 60
amps per phase to 208 volts, 3 phase, 100 amps per phase.

Water coils run around the glass laser tube to keep the tube
and the gases it contains continuously cool. The laser's water
cooling requirements are fifty pounds of water pressure and
five gallons of water flow per minute (roughly equivalent to a
standard garden hose connection). The laser emits a white
beam, which can be "mixed" by means of prisms and other
specialized optical equipment (much of which is created by
Infante for the effects he desires) to produce any color of the
spectrum. The laser can also produce tunnels, planes, cones,
and walls of light, but these effects were not used, for the
most part, in the opera.
While it is possible for Infante to custom build laser units
designed for touring for rock groups, special shows like
Faust, that use equipment from Infante's own lab, entail taking the laser equipment piece by piece, transporting it by
truck, and setting it up again at the show site. The laser unit,
which weighs about 300 pounds, the transformer (150
pounds) and the other equipment are packed and moved in
special boxes with large quantities of foam rubber to protect
the laser's glass amplifier tube from breaking.
Infante and his associate, Chris Efland, arrived at the Orpheum Theatre in downtown Boston on the Saturday afternoon prior to the Tuesday, March 21, 1978 premiere perform-
