Laser produced plasma is one of the brilliant x-ray source that has unique capabilities for use in a wide range of science. Here, we introduce that laser-produced x-ray source is very useful to simulate x-ray astronomical phenomena in the laboratory. A 0.5-keV Planckian x-ray source was created with laser driven implosion for producing non-local-thermodynamical-equilibrium (non-LTE) photoionized plasmas, which is a key to understand astronomical compact objects. Laboratory experiment of non- LTE photoionized plasma offers novel test bed for validation and verification of computational codes used in x-ray astronomy. Recently, it is demonstrated that kilo-tesla magnetic field can be generated by using capacitor-coil targets driven by high power laser beam. This strong magnetic field will offer new controll parameter to the laboratory x-ray astrophysics.
