<P>PROBLEM TO BE SOLVED: To provide semiconductor laser equipment that can reduce or eliminate a sum-wavelength noise and speckle noise, does not require any high position precision, and can be miniaturized. Ž<P>SOLUTION: The semiconductor laser equipment has: a current drive type semiconductor laser 2 utilizing emission light generated by current injection to an active layer 23 for laser oscillation as a pumping light source; and an optically pumped semiconductor laser 3 utilizing emission light generated by application of laser beams radiated from the current drive type semiconductor laser 2 to the active layer 34 for laser oscillation, as an optically pumped laser. There is a cylindrical lens 6, which reduces a divergence angle in a fast axis direction of laser beams L1 emitted from the current drive type semiconductor laser 2, on an optical axis AX1 of the current drive type semiconductor laser 2 and between the current drive type semiconductor laser 2 and the optically pumped semiconductor laser 3.
