Abstract: In this paper nature crystals of the pink and brown colored diamonds with the evident plastic deformations were comprehensively studied with IR-Fourier spectroscopy and photoluminescence methods. A- and B-centers presence were revealed by IR-Fourier specters. Femtosecond (250 fs) UV-range laser pulses with wavelength of 257, 320, 352 and 365 nm induced photoluminescence demonstrates N3 and H3 photoluminescence centers and broad structureless A-band luminescence. It was found that UV radiation with a wavelength of 257 and 320 nm does not cause A-band luminescence, which might be due to direct interband photoexcitation of diamond.

Keywords: femtosecond laser pulses, diamond luminescence, luminescence centers, ultraviolet laser radiation.
