Title: Laser welding method of thin metallic sheet
Inventor: MATSUO SHIYOUICHI
IPC: B23K26/00
Filed: 1982-08-30
Abstract: PURPOSE:To subject thin metallic sheets to laser welding with a simple installation and stage at a suitable depth, by superposing the thin metallic sheets, irradiating a laser beam thereto to provide a deep penetration with a spot of a small diameter then causing a shallow penetration with a spot of a large diameter. CONSTITUTION:The position of a lens 5 for restricting laser light is adjusted with respect to thin metallic sheets 1, 2 which are superposed on each other. The 1st pulse of the initial laser light irradiates a weld zone 3 with the beam having a small spot diameter and a large penetration depth. The lens 5 is then moved upward with the support barrel 6 thereof by means of a pulse motor 7 so that the beam of the 2nd pulse having a large diameter and a small penetration depth is applied on the weld zone 3, thereby welding the sheets 1, 2. There is no need for modification of the laser oscillator and fore-stages such as drilling or the like in this stage. Smaller peak power is required and burring on the surface arises less.

Abstract: PURPOSE: To embody a high-speed high-resolution optical recorder by branching a laser beam to multiple beams by using its polarization, modulating the generated multiple beams with a multichannel acoustic-optic modulator and executing scanning at a time. CONSTITUTION: The laser beam 1 from a laser device 15 generates two beams branched by a quarter-wave plate and Wollaston prism and is made incident on the multichannel acousto-optic modulator 14. The light emitted from a multichannel acousto-optic display device 25 is converted to a suitable beam diameter by a lens and is then passed through a roof prism 20 by which the beam is made incident on a rotary polygon mirror 21. The polygon mirror 21 keeps rotating and the multiple beams are simultaneously used to scan a photosensitive drum 24. The scanning is executed by inclining the multiple spots on the photosensitive drum in order to make the pitch of the scanning lines smaller than the intervals of the multispots. The roof prism 30 is adjusted and set by rotating the prism around its optical axis direction as its axis of rotation.  A photodetector 23 detects the signals corresponding to the respective beams which are used as the synchronizing signals for the corresponding beams.
