    • A genetic recombination laser apparatus includes an optical system having a semiconductor laser medium for generating a semiconductor laser light, an Nd:YAG crystal, an LBO and .beta.-BBOs for reducing the wavelength of the laser light, an acoustic optical device and a lens for converging the laser light with a reduced wavelength;. A stage for positioning the focus of the laser light converged by the lens at any arbitrary location on a specimen is provided. The energy of the laser light converged on the specimen is set at a value greater than the bonding energy of the substance composing the wall of the somatic cell. Preferably, the semiconductor laser light is converted into the fifth harmonic of an Nd:YAG laser light having a wavelength of 213 nm and a second harmonic with a wavelength of 532 nm generated in the conversion process is used as for positioning the focus of the laser light converged by the lens on the specimen. The laser apparatus is capable of boring a hole through the wall of a somatic cell of the higher plant for injecting foreign genetic material into the interior of the somatic cell to undergo genetic transformation.

    • A slider for the optical head easy to manufacture and having a high degree of freedom is to be provided as a slider for the optical head for recording and/or reproducing a recording medium using the proximity optical field. On a slider member 3, adapted for running on the recording medium in a state of being floated over or contacted with the recording medium, a catadioptric lens 7 is bonded to constitute a slider for the optical head 1. The slider member 3 and the catadioptric lens 7 are connected and optically unified to each other so that the numerical aperture NA of an optical system made up of the slider member 3 and the catadioptric lens 7 is not less than unity. Also, the plane of the focal point of the light incident for the side of the catadioptric lens 7 is designed to be on a recording medium facing surface of the slider member 3.
