Second-harmonic generation by an obliquely incident s-polarized laser from an underdense plasma in the presence of a magnetic field has been investigated analytically. An expression for the relativistic factor gamma has been obtained in the presence of magnetic field. The efficiency of second-harmonic radiation. has been obtained as a function of angle of incidence theta, normalized electric field amplitude of laser beam a(0), normalized electron density omega(2)(p)/omega(2), and magnetic field b. It is observed that gamma increases with b. In turn, the conversion efficiency decreases with an increase in b. It is seen that the conversion efficiency is affected by the magnetic field due to the modified relativistic factor. In the absence of magnetic field, eta increases with a(0) and theta. However, in the presence of magnetic field, the conversion efficiency starts decreasing as the magnetic field is increased.
