The single dot in magnetic field and double quantum dot with broken spin-orbital symmetry are discussed in the boson field environment. It is shown that the time dependent potential induces the Kondo effect, provided that the single boson energy compensates the spin or orbital splitting. The photon induced recovery of orbital degeneracy can occur within the same spin channel or with the spin mixing. In the former case the spin polarized photocurrent is expected.
