摘要： A liner for a shaped charge including an inner layer made of a material having a density below 10.5 g/cm3, and an outer layer made of a material having a density below 2.0 g/cm3, wherein the outer layer is formed directly on the inner layer. In a first state, both the inner layer and the outer layer are compressed towards the symmetry axis (x) of the liner, thereby forming a projectile. In a second state, the inner layer forms a penetration jet of the projectile and the outer layer forms a slug of the projectile. The melting point of the outer layer is above 100° C. The invention also concerns a shaped charge including the liner, a method for manufacturing the liner and a method for detonation of the shaped charge.

摘要： The present disclosure relates a laser arrangement (1) and a method of the laser arrangement, arranged to output energy in the form of laser emission, for emitting controlled Q-switched laser emission. The laser arrangement comprises a gain medium (2) arranged to be excited when pumped, an optical resonator (3), an active Q-switch (4) arranged in the optical resonator, said active Q-switch (4) being controllable between at least a high loss state and a low loss state, and being arranged to introduce loss in the optical resonator to prevent lasing in the high loss state and to affect lasing minimally in the low loss state, a photo detector (5) arranged to detect the presence of a free running pulse (1′) generated by the optical resonator and which occurs when a lasing threshold is reached and a processing circuitry (6) arranged to control (S4) of the state of the active Q-switch based on the detection of the free running pulse.
