question

The line width of a He-Ne laser is 10^3 Hz. The operating wavelength is 6328A° and the power is 1milliwatt. (a) How many photons are emitted per second? (b) If the output beam is 1 mm in diameter, at what temperature would a blackbody have to be in order to emit the same number of photons from an equal area and over the same frequency interval as the laser?
