摘要:

A new photoacoustic cell has been constructed to measure laser beam power. The sample, a thin brass disk, is on the front of the cell in place of the conventional window. For the thickest sample used (127 &mgr;m), the cell response was found to be linear with laser beam power up to 1.8 W, the maximum power delivered by the laser.
