One way to treat a detached retina is to weld it back in place using a laser beam.
An argon-ion laser suited for this type of operation emits 1.49×1019 photons per second,
half with a wavelength of 488.0 nm and half with a wavelength of 514.5 nm.
a) Why an argon-ion laser is suited for such a procedure?
b) What is the power output of the laser in watts at 488.0 nm?
c) What is the total power output of the laser in watts (at both wavelengths)?
d) Which laser line has the greater power output?
