Mechanism study of removing space debris with space-based free running laser
Figures & Tables(5)
Fig. 3. Pressure and impulse from different laser (Pressure and impulse data of curves were calculated from 1 cm2, impulse coupling coefficient was assumed to be 100)
Fig. 4. Power intensity of laser and diffusing depth in aluminum (Data of curves were calculated from Eq.3, the real curve stands for power intensity and the broken one for diffusing depth, which is also the depth of melting pool curve)
