Abstract :
The letter comments on the validity of assuming a constant photon lifetime in the photon conservation equation under steady-state conditions for inhomogeneously pumped lasers. An expression for photon lifetime is derived which depends on device geometry and the levels of photon fluxes in the device. The effect of this on the I/L characteristics is given.
