Abstract
An arrangement for laser spectroscopic absorption measurements comprises a semiconductor laser L having a resonator system C3 constituted by an optically active resonator c1, limited on both sides by a reflector S1, S2 and by an optically passive resonator C2 arranged adjacent the active resonator C1. The passive resonator C2 is limited on the one side by the reflector S2 of the active resonator and on the other side by a reflection grating S3. The reflection coefficient of the reflector S1, is R1 < 1, the reflection coefficient of the reflector S2 is R1 > R2 > 0, and the reflection coefficient of the reflection grating S3 is R3 > R2. The absorbing medium K to be measured is arranged in the passive resonator C2 or outside the resonator system. The detection device is arranged, either as a combination of spectrometer and registering system R, optically behind the active resonator C1, or as a registering system R only, behind the passive resonator C2. The laser may be tuned by grating S3. <IMAGE>
