摘要： An optical pickup apparatus detects optical information by making a laser beam in a 405 nm wavelength band emitted from a semiconductor laser light source incident on an optical information recording medium and then making the laser beam reflected from the optical information recording medium incident on a photodetector. The optical pickup apparatus has a polarizing beam splitter including a polarizing beam splitting film that forms an optical path from the semiconductor laser light source to the optical information recording medium by reflecting the s-polarized component of the laser beam and that forms an optical path from the optical information recording medium to the photodetector by transmitting the p-polarized component of the laser beam; and a monitoring sensor that receives the laser beam to monitor the laser output intensity of the semiconductor laser light source. The polarizing beam splitter transmits part of the s-polarized component, and the monitoring sensor receives this part of the s-polarized component in a position where the center line of the effective light beam received by the monitoring sensor does not coincide with the principal ray of that part of the s-polarized component.
