What would be the exposure irradiance (mj/cm2) in the beam of a laser pointer for a duration of 0.25 seconds if the laser has a power output of 10 mW and an aperture of 5 mm? Assume there is no significant beam divergence or atmospheric attenuation over the distance the beam travels.

If this is a crystal diode laser producing green light at a wavelength of 532 nm, would the irradiance be in compliance with the TLV for direct intrabeam ocular exposure?

TLV - TLV of 0.6 mj/cm2 for wavelength range 400-700 nm)
