We measured the dependence of the reflectivity of InSb crystals upon temper
ature in the submillimeter region using monochromatic radiation from an opt
ically pumped far infrared (FIR) laser. The measures allowed us to determin
e the value of the electron effective mass at low temperatures with radiati
ons of different frequencies. Our measurements extend the results obtained
recently on pure crystals with magneto-optical methods to the low temperatu
res region where only old measures were available.
