We investigated an ablation impulse irradiated by a nanosecond laser with an Al planar and sphere target in a large beam spot. A torsion pendulum was developed to investigate single pulsed laser ablation impulses. A beam spot size of about 1 mm diameter was selected as the large spot size because investigations have proved that a beam spot size less than 420 μm satisfied a one-dimensional plume expansion model. The results show that the minimum laser fluence corresponding to an observable ablation impulse of a planar target is about 3 J cm−2, and the optimum laser fluence corresponding to the highest impulse coupling coefficient is about 10 J cm−2 for both large and small beam spots. Our investigations prove that these two parameters are independent of the beam spot size. The impulse investigation of a sphere-shaped target reveals that its overall impulse is lower than that of a planar one irradiated by a large laser beam spot in high laser fluence regimes, especially when a strong plasma plume event is happening. This phenomenon may be caused by different plasma plume propagation directions due to a non-flat surface of the sphere targets because the plume expansion by nanosecond laser ablation is mainly normal to the local surface.

Conventional propellant materials, such as polymers and single metal elements, have long been investigated for their potential in pulsed laser micropropulsion (LMP) technology. However, achieving superior LMP efficiency through physical mixing of these materials remains a significant challenge. In this study, we present a paradigm shift by introducing porous crystalline polymers, known as Metal‐Organic Frameworks (MOFs), as novel propellants in pulsed LMP. MOFs are composed of metal cations and organic ligands that form ordered structures through coordination, eliminating the problem of local hot zones arising from uneven physical mixing encountered in LMP. In direct comparison to conventional polymers and single element targets, MOFs exhibit substantially higher LMP efficiency. By precisely tailoring the metal atom fraction within MOFs, an extraordinary ultrahigh efficiency of 51.15% is achieved in pulsed LMP, surpassing the performance of similar materials previously reported in the literature. This pioneering application of MOFs not only revolutionizes the field of laser micropropulsion but also opens up new frontiers for MOF utilization in various energy applications.This article is protected by copyright.

“…Since laser propulsion was first proposed by Kantrowitz in 1972 [1], it has been extensively studied because of high payload efficiency, wide range of thrust adjustment, and low launch cost [2][3][4]. Laser propulsion is potentially applied in the aerospace field, such as microsatellite launch into near-Earth orbit, space debris removal, attitude adjustment and orbit control of satellites [2,[5][6][7].…”

Propulsion performance produced by laser ablation of polymer made of acrylonitrile butadiene styrene (ABS) is experimentally investigated using the first, second, and third harmonics of a Nd: YAG laser. A ballistic pendulum is employed to assess the impulse and coupling coefficient for laser propulsion application. Fast photography, target ablation, and optical emission spectroscopy are proposed to analyze the energy coupling characteristic. The impulse and coupling coefficient under different pressures are demonstrated to depend on the target ablation and plasma properties which are relevant to laser wavelength. As the laser wavelength decreases, the crater depth and ablation mass are enhanced. Meanwhile, the plasma plume separates at atmospheric pressure and its length extends continuously in the low-pressure range. As a result, plasma including more ejected particles with higher velocity contributes to obtaining excellent impulse and coupling coefficient. In addition, the decreased electron density and temperature indicate higher collision frequency and photoionization dominate rather than inverse bremsstrahlung absorption at shorter laser wavelengths. This work provides a better understanding of the energy conversion mechanism and a reference for improving propulsion performance.
