For a gaas, the fresnel reflection coefficients for uncoated facets are 0.32 and a 10 cm. determine the lasing threshold condition for a laser diode of length 500 pum

lasing threshold condition is 32.78 cm

Explanation:

given data

uncoated facets R = 0.32

a =  10 cm

length L = 500 um = m

to find out

lasing threshold condition

solution

we know lasing threshold condition formula that is

lasing threshold  = a - ln   ..........1

put here all value in equation 1 we get

lasing threshold  = a - ln  

lasing threshold  = 10 - ln  

lasing threshold  = 32.78

so lasing threshold condition is 32.78 cm

they start with the same

another example of kinetic energy would be,

kinetic energy   >     moving energy
