It is shown that an increase in the internal losses beyond the lasing thres
hold in the lasers based on InGaAsSb/InAsSbP double heterostructures (wavel
ength range lambda = 3.0-3.6 mu m, temperature T = 77 K) causes the current
-related shift of the laser mode to shorter wavelengths. This shift is as l
arge as 80 cm(-1)/A and can explain the broadening of the laser line from 5
to 7 MGz as the pump current increases. (C) 2000 MAIK "Nauka/Interperiodic
