Apparatus for producing high repetition rate optical pulses, including:
- a pulsed laser operating at a first laser frequency that produces an initial laser beam operating at an initial pulse rate and having an initial laser frequency;
- a laser frequency converter that increases the initial laser frequency to produce a second laser beam having a second, higher, laser frequency;
- and
- a pulse repetition rate multiplier, which receives the second laser beam and produces at least one pulsed third light beam, having a higher pulse repetition rate than the initial rate.
A method for producing light repetition rate laser pulses, comprising:
- providing a first laser beam pulsed at a first pulse repetition rate and having an initial laser frequency;
- converting the laser frequency to a higher frequency to produce the a second pulsed beam at a second laser frequency higher than the initial laser frequency and having the initial pulse repetition rate;
- multiplying the pulse rate of the second pulsed light beam to produce at least one third pulsed light beam having a higher pulse repetition rate than the first rate.
Apparatus for transmitting information at a data rate, comprising:
- a pulsed light source that produces a first pulsed light beam having an initial pulse repetition rate;
- a pulse repetition rate multiplier, which receives the first pulsed light beam and outputs at least one second pulsed light beam having a higher pulse repetition rate than the initial pulse repetition rate;
- and
- a modulator that modulates the at least one second pulsed light beam at the data rate.
Apparatus for recording an image on a photosensitive surface at a data rate, comprising:
- a pulsed light source that produces a first pulsed light beam having all initial pulse repetition rate;
- a pulse repetition rate multiplier, which receives the first pulsed light beam and outputs at least one second pulsed light beam having a higher pulse repetition rate than the initial pulse repetition rate;
- a modulator that modulates the at least one second pulsed light beam at the data rate;
- and
- a scanner that scans the modulated at least one second pulsed light beam over the surface to record an image on a photosensitive surface.
A method of transmitting information at a data rate, comprising:
- providing a first pulsed light beam having an initial pulse repetition rate;
- multiplying the first pulsed light beam to produce at least one second pulsed light beam having a higher pulse repetition rate than the initial pulse repetition rate;
- and
- modulating the at least one second pulsed light beam at the data rate.
Apparatus for recording an image on a photosensitive surface, comprising:
- a pulsed light source that produces a primary pulsed light beam having a pulse repetition rate that is substantially higher than a data rate;
- a light wavelength converter, separate from the pulsed light source, that receives the primary pulsed light beam, and produces a second, ultraviolet pulsed light beam responsive thereto;
- a modulator that modulates the pulsed light at the data rate;
- and
- a scanner that scans the modulated pulsed light over the surface to record an image on the photosensitive surface.
A method for recording an image on a photosensitive surface, comprising:
- producing a primary pulsed light beam having a pulse repetition rate that is substantially higher than a data rate;
- converting the primary light beam, in a light wavelength converter separate from the pulsed light source, to a second, ultraviolet pulsed light beam;
- modulating the pulsed second beam at the data rate;
- and
- scanning the modulated pulsed light over the surface to record an image on the photosensitive surface.
