    Hello Cheng,

    Welcome to the DLP section of the TI-E2E forums.

    Assuming that your diameter is at FWHM (full width half max) and that the power is over the entire Gaussian surface of rotation, then the power at the peak would be about 4.4 W/cm^2, which should fine if you properly dissipate the heat with a heat sink.

    This assumes a CW laser.  If you are going to use a pulsed laser and the 5W is the time average power, then you must also determine the peak power density using the pulse duration and repetition rate.

    Please review the following Application Note:  Laser Power Handling for DMDs
