1 Nonlinear-optical approach to problem of space debris tracking and removal O. Kulagin, I. Gorbunov Institute of Applied Physics Russian Academy of Sciences, N.Novgorod, Russia
2 Space debris threats and application of phase conjugation methods for concentrating the debris illumination Nearly 90% of orbital debris has dimensions ~ 1-5 cm. This debris is not tracked. Debris removal demands a high density in illumination laser energy, though it is restricted by the atmospheric turbulence. Space debris illumination concentration by laser point narrowing can be achieved by means of phase conjugation of the debris scattered illumination. When phase conjugation compensates for turbulent distortions, the conjugated signal will be concentrated on the debris to an accuracy that is determined not by the turbulent scattering angle (~10-5 rad), but instead by the receiving aperture of laser amplifier (e.g., ~ rad for the primary mirror of 00 cm).

4 Nonlinear optical (BEFWM) laser image amplifier PC-mirror lens Object plane Input lens Laser amplifier PC- mirror via BEFWM Beam-splitter Image plane The sensitivity is limited by quantum noise and is near J (approximately two photons) per pixel; Extremely narrow frequency band corresponds to two frequency-temporal modes (input spectral band ~ nm and response time of ~ 30 nsec); Comparatively wide field of view (350 Х 350 pixels in image); High coefficient of amplification (amplifies weak signal by ~ 10 1 ).

10 Active impact on space debris using intense lasers Physical mechanisms of recoil impulse generation: Developed surface evaporation of the debris The maximum efficiency of recoil impulse at laser intensity of I ~ 10 6 W/cm Optical breakdown in the vapor. Laser-plasma absorption For near IR lasers ( =1.06 µm): I > W/сm

A Review of the ORION Concept for Space Debris Mitigation. International Orbital Debris Removal Conference. Chantilly, Virginia, 009 Recoil change of energy and angular momentum: E L E 1 E 0 m ( v 1 v 0 ) p p v m 0 Elliptical orbit: E 1, v 1, L 1, p 1 SD object: m = 1 kg; v 0 = 7.6 km/с at r 0 = R з + h 0 = 6371 km km this SD object shifts to desirable r min = 00 km p r0 L if recoil momentum is provided p = 114 kg m/с 1 L0 taking into consideration a mass defect Δm caused by evaporation we have p = kg m/с
12 Laser energy evaluation for SD object propulsion It is assumed for SD m = 1 kg, velocity v 0 = 7.6 km/c a rebound velocity of vapoured part v Al (in the movable frame of reference) we have got v Al from relation: m1 mal val 3 kt For Aluminium atom m Al кг And temperature T = 770 K v Al = 1.60 km/с and p m p Δm = 6.7% m m 1 v 1 m 1 v 0 m v 0 m v We have got a desirable energy of laser pulse by using Aluminium parameters Melting heat λ = J/kg Evaporation heat L = J/kg Heat capacity c = 930 J/(kg К) W = Δm(λ+L+cΔT) = Δm( ) = 807 kj As a conclusion, a laser pulse energy of 1 kj (at repetition rate of 100 Hz and efficiency of conversion into the recoil pulse ~10%) is acceptable to provide desirable propulsion during one pass of SD object by orbit Hence, a laser output ~ 1kJ x 10 ns x 100 Hz looks sufficient for small LEO orbital debris removal using non-linear optical laser energy concentration. 1
13 Possible full-scale experiment of model SD object control by laser amplifier with BEFWM Purposes: Measurements of recoil pulse; Investigation of SD movement dynamics (rotation, oscillations, etc.); Influence of SD material and laser parameters model SD Model SD object with retroreflectors (~1 kg; 10-0 cm) LA BEFWM Laser-rangemeter IL MO Pump Laser The poor quality primary mirror is acceptable because of using phase conjugation technique. Laser parameter combination of 30 J x 10 ns x 30 Hz is enough to shift a model LEO object by ~ 100 m of orbit height due to the laser recoil 13 impact during one orbital pass
