Abstract. In recent years, a large number of linear and nonlinear laser-based diagnostic techniques for detection of pollutions in different environments have been developed. Applications of laser spectroscopy constitute a vast field, which is difficult to cover comprehensively in a review. Due to that, here are presented only a few spectroscopic methods, chosen to illustrate the power of applied laser spectroscopy in environmental pollution investigation. The paper also gives a brief presentation of main laser spectroscopy methods.
Key words:  Laser spectroscopy, trace gas detection, optoaocoustic spectroscopy.

UPOTREBA LASERA ZA ISPITIVANJE POLUTANATA Poslednjih godina razvijen je velik broj raznovrsnih instrumenata zasnovanih na laserskim sistemimima. Oni omogućuju da se može pouzdano i u realnom vremenu uraditi monitoring okoline, industrijskih procesa, monitoring bioloških funkcija čoveka, selektivna detekcija molekula u tragovima... Uporedo sa razvojem novih laserskih i detekcionih sistema razvijen je niz linearnih i nelinearnih dijagnostičkih metoda za nedestruktivna merenja koncentracija polutanata u različitim sredinama. Kako je teško pokriti široku primenu lasera u rešavanju problema vezanih za zaštitu čovekove okoline, ovde je dat kratak prikaz, nekih savremenih metoda.
