  In this study, we investigate the cyclotron resonance effect in the
first-order AC current, magnetic ratchet effect, and second harmonic generation
in phosphorene in the presence of a steady tilted magnetic field and under THz
laser radiation. We establish that various cyclotron resonances exist in the
deduced currents based on the angular frequency of the incoming light. These
resonances are dependent on the $\omega_{c_{+}}$ value, a function of the
carrier charge, the perpendicular magnetic field, and the effective masses
along the armchair or zigzag edges. We discuss the direction and the magnitude
of the deduced currents for various radiation polarizations. We compare the
results with a zero perpendicular magnetic field. Cyclotron resonance for the
first order AC current occurs at $\omega= \pm \omega_{c_{+}}$. The deduced
current declines if the perpendicular magnetic field is zero. Meanwhile, for
the ratchet current, cyclotron resonances occur at $\omega= \pm
\omega_{c_{+}}$, $\omega= \pm 2\omega_{c_{+}}$, and radiation helicity affects
the deduced current for circularly polarized light. Cyclotron resonance for the
second harmonic generation current occurs at $\omega= \pm \omega_{c_{+}}$,
$\omega= \pm 2 \omega_{c_{+}}$ and $\omega= \pm \omega_{c_{+}}/2 $ and the
current is stronger compared to the case with no perpendicular magnetic field.
As the magnetic field rotates in the plane of anisotropic phosphorene, separate
directions are predicted for the second harmonic generation--related current.
It is noteworthy that the magnitude of the ratchet and second harmonic
generation current are within the same range and comparable to the magnetic
ratchet current in monolayer graphene, $\mu A / cm$.
