We demonstrate direct microwelding between glass and copper substrates by use of femtosecond (fs) pulses. The joint strength is as high as > 16MPa. A scanning electron microscopy cross-sectional image of the sample proves successful joining without voids or cracks. Furthermore, we show that, compared with ns-pulses, the use of fs-pulses can reduce the pulse energy required for welding by two orders of magnitude, leading to the suppressed effect of heat and to the precise control of the welded region.
