A typical handheld red laser pointer outputs laser light of
wavelength 650 nm with a power of 5.0 mW. This power is equivalent
to 0.005 Joules of energy output per second.
a) How much energy does one of these red photons have? Answer in
Joules.
b) How many photons does this laser produce every second?
Draw and label a diagram of a continuous gas laser, such as a
Helium-Neon laser.
An important type of laser for industrial applications is the
Carbon Dioxide (CO2) laser. Research the CO2 laser. How does it
work? What wavelengths does it emit? Is it based on the same
principle as a He-Ne laser?
