What is the lasing wavelength

Reference no: EM13272217

A three level laser has energy levels E 1=1.50 eV, E 2=2.50 eV, and E 3=3.50 eV. Level E 2 is the metastable state.

a) If the laser is pumped optically, what pump wavelength should be used?

b) What is the lasing wavelength?

c) If 1.00 W of pump power is used, and the laser's output coupler has a reflectivity of R=0.95, what is the maximum output power of the laser? Assume that every pump photon is converted into a lasing photon via stimulated emission.
