“…Published values of the exponents n 1 , n 2 vary widely, depending on the emission wavelength, the manufacturing process and the geometry of the HPLD chip. Some published values are n 1 , n 2 = 2, n 1 = 0, n 2 = 5.7 and n 1 = 0, n 2 = 2.3 . For a conservative estimate of the time to failure, we assume the likely scenario that with n 1 = 0, the degradation because of an increased current density has a negligible influence compared with effects resulting from optical excitation such as catastrophic optical damage of a laser mirror, which effect we take into account by assuming n 2 = 2.…”

“…For lasers employing double heterostructure an important requirement is that the layers of semiconductor materials must be lattice-matched. Semiconductor lasers with Al-free materials (InGaAs/InGaP) have higher power conversion efficiencies due to their lower differential series resistance and higher conductivity [26][27]. In addition, an Al-free material has very tight carrier confinement and optical power densities (18-19 MW cm -2 ) at catastrophic optical mirror damage (COMD).…”
