Abstract: A delay device is provided that includes at least one first optical guide for receiving an optical signal, and at least one optical means for outputting a delayed optical signal. A plurality of total signal reflection means are placed along the first optical guide, and a plurality of second optical guides are placed between the reflection means of the plurality of reflection means and the at least one optical means. An activation means activates at least one of the reflection means, and selection means select which of the reflection means of the plurality of reflection means is to be activated to obtain a desired delay on the optical path of the optical signal. The reflection means are placed in succession along the first optical guide. Also provided is a transmission system that includes at least one laser source, an emission source, and at least one such optical delay device.

Abstract: The performance of free electron lasers can be greatly enhanced by including a non-linear optical element within the resonator for the oscillator. A system is described to enhance the peak or average power output of the FEL oscillator, or to modify the time structure of the oscillator output through the use of a non-linear element which modulates or diverts a portion of the optical wave circulating in the resonator.

Abstract: A technique for the simultaneous measurement, in real time, of the changes in mode size, pulse length, and power of a wavetrain of laser pulses delivered by mode-locked or other pulsed laser systems contemplates directing respective portions of the beam along each of three beam paths. The beam portions along the first and second beam paths are subjected to respective, and different, degrees of focusing, and then passed through respective non-linear elements which generate radiation at the second harmonic. The first harmonic components are removed, and the second harmonic components are passed to respective first and second detectors which generate signals representative of the total second harmonic energy along each of the first and second beam paths. The beam portion along the third beam path is passed to a detector which generates a signal representative of the total energy in the beam pulse. The three signals are combined to give values proportional to peak power, pulse length, and mode size.
