Abstract
A device is disclosed for producing a pair of synchronized intense 16 micron pulses in which stimulated rotational Raman scattering together with four wave mixing and pulse compression takes place in parahydrogen on an off-axis path between a pair of spherical mirrors.
Claims8
Apparatus responsive to a first pair of at least partially overlapping optical pulses for generating a second pair of optical pulses, said apparatus including:
- a medium capable of producing stimulated scattering of radiation occupying a volume;
- means for defining a multipass optical path through said volume, said optical path intersecting itself;
- means for directing a first of said first pair of optical pules along said optical path, said first of said first pair of optical pulses having a full width at half maximum equal to or greater than the transit time of said first of said first pair of optical pulses for one pass of said multipass optical path defining means;
- and
- means for directing a second of said first pair of optical pulses along said optical path, said second of said first pair of optical pulses having a full width at half maximum equal to or greater than the transit time of said second of said first pair of optical pulses of one pass of said multipass optical path defining means thereby providing said second pair of optical pulses.
