The invention relates to a vertical cavity surface emitting laser and method for fabricating the same. The vertical cavity surface emitting laser of the invention comprises: a substrate, a first reflector, an active layer, a second reflector, a first electrode layer and a second electrode layer. The second reflector has a first confinement layer with a first aperture and a second confinement layer with a second aperture. The second aperture is smaller than the first aperture. According to the invention, because the second confinement layer is formed by implanting oxygen ion into the second reflector and heating to let the oxygen ion and Al content in the second reflector react to form an oxide layer, the second confinement layer can be used as an optical and electronic confinement layer. Therefore, the width and depth of the second confinement layer can be achieved precisely and easily.

The invention discloses an ultrasonic quilting main machine which comprises a left side box body, a left side plate, a generator support, a right side plate, a right side box body, an edge cutting ultrasonic fixed sliding rail, a fixed lower beam, a cloth trend, a transmission part, a flower roller adjusting part, an ultrasonic part, an edge cutting part and a centrifugal fan. Cloth penetrates in from the upper portion of the first scutching roller from the rear portion from bottom to top, passes through the lower portion of the second scutching roller, the upper portion of the ultrasonic embossing roller, the lower portion of the cloth passing roller, the position between the edge cutting embossing wheel and the second ultrasonic welding head and the position below the first cloth outlet rubber coating roller, and finally penetrates out from the position between the first cloth outlet rubber coating roller and the second cloth outlet rubber coating roller. According to the invention, the use requirement of customers on the edge-cutting welding spots of the cloth finished products is met, and the widths of different cloth finished products are realized by adjusting the position of the edge-cutting part on the guide rail sliding block and the position of the ultrasonic mounting plate II on the edge-cutting ultrasonic fixed sliding rail; and the replacement of the ultrasonic embossing roller is realized by virtue of an auxiliary part, namely the embossing roller replacement support, so that the requirements of different patterns are met.

The invention discloses a joint production line for a spun-laced nonwoven fabric. The joint production line comprises a placing base plate; one end of the placing base plate is fixedly provided with abox body; a drying device is arranged inside the box body; the two sides of the box body are each provided with an inlet and an outlet; one side of the box body is provided with an air cooling device; the air cooling device is provided with a winding device at one side of the box body; a pressing device is arranged above the winding device; the drying device comprises a fan; one end of the fan isprovided with an air inlet hood; the end of the fan away from the air inlet hood is provided with a communication pipe; the end of the communication pipe away from the fan communicates with a heatingbox; a plurality of heating nets are arranged inside the heating box; and an L-shaped pipe is arranged at one end of the heating box away from the communication pipe. The joint production line has the beneficial effects of being simple in structure and convenient for adjustment, operation and use, reducing the labor intensity of a worker, and greatly improving the work efficiency.
