The performance of a tunable diode laser (DL) spectrometer is directly dete
rmined by the DL qualities and its tunability control. Emission characteris
tics are very sensitive to current and temperature drifts. In order to obta
in a high quality source for spectroscopy, we designed our own liquid nitro
gen cryostat containing the DL. Moreover we compared current and temperatur
e control and we found that temperature tuning can be more efficient. We ch
eck and demonstrate it by recording SO2 spectra in the 1168-1169 cm(-1) spe
ctral region. (C) 2000 Elsevier Science B.V. All rights reserved.
