  Recent years have seen tremendous progress in our understanding of the
cosmos, which in turn points to even deeper questions to be further addressed.
Concurrently the laser technology has undergone dramatic revolutions, providing
exciting opportunity for science applications. History has shown that the
symbiosis between direct observations and laboratory investigation is
instrumental in the progress of astrophysics. We believe that this remains true
in cosmology. Current frontier phenomena related to particle astrophysics and
cosmology typically involve one or more of the following conditions: (1)
extremely high energy events; (2) very high density, high temperature
processes; (3) super strong field environments. Laboratory experiments using
high intensity lasers can calibrate astrophysical observations, investigate
underlying dynamics of astrophysical phenomena, and probe fundamental physics
in extreme limits. In this article we give an overview of the exciting prospect
of laser cosmology. In particular, we showcase its unique capability of
investigating frontier cosmology issues such as cosmic accelerator and quantum
gravity.
