About the paper Full textAbstract
Picosecond lasers are widely used in various industrial and scientific applications. One of them is high-precision satellite laser ranging. The current state of the art for high-precision satellite laser ranging requires stable and reliable lasers with short pulse duration, high pulse repetition rates, and a high level of resistance to the ambient environment in order to achieve the highest measurement accuracy. Here we report on the development of Nd:YAG laser based on «master oscillator — regenerative amplifier — second harmonic generation» approach and applied for high-precision satellite laser ranging. A picosecond laser diode operating in the gain switch mode is used as a master oscillator. The regenerative amplifier is based on two Nd:YAG rods ⌀6 × 30 mm with diode end pumping. The LBO crystal 5 × 5 × 10 mm with type II phase matching is used as the second harmonic generator. Laser delivers 35 ps pulses at 532 nm wavelength with > 2.5 mJ pulse energy with < 2 % energy stability (RMS). The second-harmonic conversion efficiency was up to 65 %. The pulse repetition rate is 300 Hz (up to 1000 Hz is possible). The beam divergence is 0.3 mrad at $1⁄e^2$ intensity level for a beam diameter at the laser output of 3.4 mm. The main feature of the developed system is the possibility to operate at ambient temperatures from –40°C to +40°C that is achieved by proper thermal management: liquid thermal stabilization of the laser body using a chiller, as well as the use of a system of flexible heaters and multilayer thermal insulation. The laser is installed on the «Sazhen-TM» rangefinder in the observatory «Svetloe». The short pulse duration, high stability of the pulse shape and the pulse energy, as well as the possibility to operate in a wide range of ambient temperatures make this laser a demand tool for high-precision satellite laser ranging.

laser ranging. The current state of the art for high-precision
satellite laser ranging requires stable and reliable lasers with
short pulse duration, high pulse repetition rates, and a high level
of resistance to the ambient environment in order to achieve the

Nd:YAG laser based on «master oscillator — regenerative amplifier —

satellite laser ranging. A picosecond laser diode operating in the
gain switch mode is used as a master oscillator. The regenerative
amplifier is based on two Nd:YAG rods ⌀6 × 30 mm with diode end
pumping. The LBO crystal 5 × 5 × 10 mm with type II phase matching is
used as the second harmonic generator. Laser delivers 35 ps pulses
