Paper Abstract

In the paper, a technique termed time-resolved spectra mapping, developed to assess thermo-optical properties of pulse operating lasers, is described. The technique enables measurement of the laser mode spectral characteristic at an arbitrarily elected moment within the width of the driving current pulse. The measured shift of the central mode wavelength in the spectrum envelope serves then to determine temperature change of the laser active region. The timeresolved spectra mapping technique has been found useful in evaluation of the efficiency of heat removal from lasers mounted in different packages.
