摘要： An output laser beam of an unstable laser resonator has a circular cross sectional pattern, so that a condensation thereof becomes easy, resulting in a high power beam. The circular pattern is obtained by making an expanding mirror of the resonator partially transmissible and compensating for a phase difference between laser beam portions passing through the expanding mirror and other portion of a window mirror.

摘要： A dichroic mirror for reflecting red light for optical separating and a dichroic mirror for reflecting red light for optical synthesizing are installed on the same plane in an image generating apparatus of the present invention. In addition, a dichroic mirror for reflecting blue light for optical separating and a dichroic mirror for reflecting blue light for optical synthesizing are installed on the same plane. Accordingly, a compact configuration can be realized. Since a main reflecting mirror is a rotating elliptic mirror and a lamp is located on a focus or around the focus, a lighting equipment which irradiates conic luminous flux can be realized.

摘要： An optical processing apparatus utilizing multiple reflections of a light beam between a mask and a reflector has improved uniformity in the distribution of the light beam over a surface of the mask. In one form, the reflector is disposed in a face-to-face relation with respect to the mask with an angle of inclination relative thereto. In another form, the reflector has a flat or curved taper surface for decreasing an angle of reflection of the light beam at the mask surface at an initial stage, and a flat surface disposed in parallel with the mask surface. In a further form, the reflector is curved in a direction of transmission of the light beam. In a yet further form, an angle of incidence of the light beam is properly adjusted such that a portion of the light beam, which is first reflected from the mask and escapes outwardly from the reflector, is minimized.
