Frequency tuning of PbTe injection lasers by combined action of pressure and temperature

Frequency tuning of PbTe injection lasers by combined action of pressure and temperature

The radiation emitted from a PbTe injection laser was tuned in the wavelength range 5--9.6 ..mu.. using an independent optical high-pressure chamber and a cryostat with a consinuously flowing cooling agent. The wide-range (within 600 cm/sup -1/) pressure tuning was combined with continuous temperatu...

Zusammenfassung:The radiation emitted from a PbTe injection laser was tuned in the wavelength range 5--9.6 ..mu.. using an independent optical high-pressure chamber and a cryostat with a consinuously flowing cooling agent. The wide-range (within 600 cm/sup -1/) pressure tuning was combined with continuous temperature tuning (within 400 cm/sup -1/). The pressure was varied from 0 to 12 kbar and the temperature from 4 to 120/sup 0/K. The system was used in a laser spectrometer.
