SOME APPROACHES TO VACUUM UV AND X‐RAY LASERS
The ejection of electrons from inner shells of atoms through photoionization is suggested as a straightforward means of creating population inversions at vacuum uv and x‐ray wavelengths. This can beExpand
Optoelectronic regenerative pulser
The letter describes a new scheme for generating repetitive picosecond laser and electrical pulses in a controlled manner. The arrangement is a feedback loop containing a semiconductor diode laser, aExpand
Optical sampling of subnanosecond light pulses
Soft x-ray gain in the alkali earths.
An unsuccessful attempt was made to observe gain in low pressure sodium vapor at 372 A at an x-ray pumping power level of 0.1 GW/cm(2) . As a result we suggest that high density alkali-earth vaporsExpand
IV The Ultrafast Optical Kerr Shutter
Publisher Summary One particularly useful application of picosecond laser pulses, which is the object of this chapter, has been in the development of an ultrafast shutter (or gate) based on theExpand
Ultrahigh speed photography of picosecond light pulses and echoes.
Three new results have been obtained with a recently developed camera of 10-psec framing time: (1) The effect of the finite speed of light in photographing relativistic objects is experimentallyExpand
AN ULTRAFAST LIGHT GATE
A simple technique is described for gating light on and off on the picosecond time scale. The gate is built in much the same fashion as traditional Kerr cells, the difference lying in the use ofExpand
Direct measurement of picosecond lifetimes
Abstract A generally applicable technique is introduced for the direct measurement of lifetimes on the picosecond time scale. Use is made of a new type of Kerr cell which is activated by laser pulsesExpand
Compression of optical pulses
A scheme, similar to one used in the chirp radar, is proposed to compress in time, without loss of energy, the light pulse generated by a mode-locked laser. On the basis of preliminary experimentalExpand
An ultrafast light gate
A device has been built which is capable of gating light on and off on the picosecond time scale. The gate is built in much the same fashion as traditional Kerr cells, the difference lying in the useExpand
