Description: A power meter was constructed to measure the power being deposited in transient laser-induced plasmas (LIP). The design rejects the radiation scattered from the laser beam by the LIP and that transmitted past the LIP. The power meter is constructed from a small metal-capped flask placed in an evacuated chamber. The steady-state heat production in the flask is determined from measurements of the temperature gradient on a thermal resistance connecting the top of the flask with a heat sink. The design worked well and should be applicable to a wide variety of situations if the dimensions of the system are adjusted to compensate for power levels substantially different from those used here.
