Embodiment Construction

[0043] Detailed reference will now be made to the preferred embodiments of the present invention. These embodiments are shown in the accompanying drawings.

[0044] The present invention relates to methods of wet laser drilling of transparent bodies 10 such as glass or sapphire. This method can advantageously be used to manufacture the optical devices described in this specification. These optical devices may be fiber optic devices for securing optical fibers, such as fiber optic ferrules.

[0045] like Figures 1A-1C As shown, the method includes providing an ultrashort pulse laser 30 for generating a laser output 32 at a wavelength λ having a sub-picosecond laser pulse duration. Preferably, the transparency of the light-transmitting body 10 at λ is at least 90% / cm and preferably ≥95% / cm, and the absorptivity at λ is less than 5×10 -2 cm -1 . Preferably, the volume thickness of the transparent body is at least 0.5 mm, more preferably 1 mm, most preferably at least 2 mm. ...

Abstract

A method of making an at least one hole in an optically transparent body (10) comprises the following steps: (i) providing an ultrashort pulse laser for producing a laser output with a wavelength , the laser output having a subpicosecond laser pulse duration; (ii) providing a laser output focusing lens (34) for focusing the laser output, the focusing lens (34) having a numerical aperture NA; (iii) providing an optically transparent body (10), the optically transparent body (10) having a transparency at of at least 90% / cm; (iv) providing a liquid (39') filled container (39) situated proximate to the optically transparent body (10), such that the optically transparent body (10) is in direct contact with the liquid (39'); and (v) directing the laser output through the focusing lens (34) to produce a focused laser output with a subpicosecond laser pulse duration proximate the optically transparent body (10), wherein the focused laser output traces at least one hole track pattern through the transparent glass body while the optically transparent body (10) and said focused laser output move relative to one another in X-Y-Z directions . The at least one hole track pattern is in contact with the liquid and the focused laser output, in conjunction with the liquid (39'), creates at least one hole in the optically transparent body (10).
