Characteristics
a. Good Thermal Conductivity
b. Lower lasing threshold and higher slope efficiency
c. Large stimulated emission cross-section at lasing wavelength
d. High absorption over a wide pumping wavelength bandwidth
e. Low dependency on pumping wavelength and tend to single mode output
f. Optically uniaxial and large birefringence grants strongly-polarized laser emission
