Abstract

The tasks of lunar laser ranging in astronomy require an increased capacity of observation sessions and about 1 mm measurement accuracy. These improvements imply the necessity to use modern laser sources with short pulse duration, high pulse repetition rate and the sub-joule (or higher) output pulse energy range. Using two-colour laser systems in the satellite ranging makes it possible to take into ac-count the influence of the Earth’s atmosphere on the time of light propagation to the aim. The short pulse duration in the lasers of this type causes the necessity of solving tasks associated with the low level damage threshold of optical coatings and the effect of small-scale self-focusing. Also, it is impossible to use the SBS-mirrors to compensate for thermally induced distortions of the wavefront in the lasers with less than 1 ns pulse duration. This paper presents the development report about the compact two-colour (1064 nm and 532 nm) laser with a very stable output pulse shape. The laser generates pulses with the energy of 0.5 J and pulse duration of 71 ps at the 1064 nm wavelength. The 0.3 J and 63 ps pulses are generated at the 532 nm wavelength respectively. The pulse repetition rate of the laser is 200 Hz.

AB  - The tasks of lunar laser ranging in astronomy require an increased
capacity of observation sessions and about 1 mm measurement accuracy.
These improvements imply the necessity to use modern laser sources
with short pulse duration, high pulse repetition rate and the sub-
joule (or higher) output pulse energy range. Using two-colour laser
systems in the satellite ranging makes it possible to take into ac-
count the influence of the Earth’s atmosphere on the time of light
propagation to the aim. The short pulse duration in the lasers of
this type causes the necessity of solving tasks associated with the
low level damage threshold of optical coatings and the effect of
small-scale self-focusing. Also, it is impossible to use the SBS-
mirrors to compensate for thermally induced distortions of the
wavefront in the lasers with less than 1 ns pulse duration. This
paper presents the development report about the compact two-colour
(1064 nm and 532 nm) laser with a very stable output pulse shape. The
laser generates pulses with the energy of 0.5 J and pulse duration of
71 ps at the 1064 nm wavelength. The 0.3 J and 63 ps pulses are
generated at the 532 nm wavelength respectively. The pulse repetition
rate of the laser is 200 Hz.
