Abstract: We present the observation of coherent population trapping resonances on the second resonance line of potassium: 4s(2)S(1/2) -> 5p(2)P(3/2) with wavelength of 404.4 nm. Moreover, a transfer of the coherent population trapping resonance occurs to the excited 4p(2)P(1/2) and 4p(2)P(3/2) states of the first resonance line due to cascade transitions. This transfer is evidenced by the observation of narrow resonances at the infrared 4s(2)S(1/2) -> 4p(2)P(1/2) and 4s(2)S(1/2) -> 4p(2)P(3/2) transitions when alkali excitation is performed at the 404.4 nm violet line.
