Femtosecond Two-Wavelength Laser Ranging To The Ground Target

Two-wavelength laser ranging experiments with subpicosecond temporal resolution are described. To provide these experiments a reliable passively mode-locked Nd:YAP laser with two saturable dyes in the same laser cavity was specially designed. For laser pulses recording the commercial anglo-soviet Imacon 500 streak camera fitted with the PV-00l tube and matched with SIT-vidicon and computer data handling system were employed. The possibilities for further increasing of resolution and other recording characteristics of the developed installation are briefly discussed.
