Astrophysical jets which are launched from the system of central object and surrounding accretion disk. The astrophysical jets propagate so long distance into the ambient gas, keeping well collimated structure due to the confinement by the high pressure cocoon. I will briefly introduce hydrodynamic instabilities which are recently discussed by some groups. Then I will discuss possible future experiments by ultra-intense lasers.
