Explain the lasering process on Carbon dioxide laser,
Nd: YAG laser, and HeNe laser in details and show the energy levels
for lasing for example in Co2laser the 9.6 and 10.6-micron laser
lines.
A particular HeNe laser operating at 632.8 nm has a tube that is
40 cm long. The operating gas temperature is about 130 C.
Calculate the frequency separation and the wavelength
separation of the laser modes. How do these change as the
tube warms up during operation? Taking the linear expansion
coefficient to be 10-6 K-1, estimate the change in the mode
frequency separation.
(please calculate the frequency separation and the wavelength
separation)
Explosive Entertainment Inc. (EEI) is a wholesaler that sells
three lines of sound systems. Pertinent details of the company
follow:
• EEI purchases and resells the outdoor Product A and jogging
Product B sound systems without alteration. For its indoor Product
C sound system, EEI purchases the three component parts from
separate producers and then assembles the finished product on its
premises.
• EEI tracks its inventory using a perpetual inventory system
and values it using the weighted average cost...
1) Summarize the conditions of Laser operation and explain
shortly the essentials of He-Ne laser
operation.
2) A laser diode has dielectric constant of ε = 4εo and has a
cavity length 1-mm long
with one perfect mirror and one mirror with a power reflection
coefficient of 0.99. It
operates at wavelength of 1-micron with linewidth of 0.1 percent
associated with the
width of the energy levels involved. (a) What is the frequency
spacing (Hz) between
resonances for this laser...
