Abstract

The invention relates to a semiconductor laser device comprising a laser bar (2), a flexible conductor support (10), a supporting body (3) of a metal or a metal alloy and a heat sink (4), which is arranged between the supporting body (3) and the laser bar (2), the laser bar (2) being electrically contacted by the flexible conductor support (10) and the supporting body (3) having a thickness of at least 2 mm. The invention further relates to a method for producing the above-described semiconductor laser device, wherein a synchronous soldering process is used to solder the laser bar (2) to the heat sink (4) by means of a hard solder layer (30) and the heat sink (4) to the supporting body (3) by means of a further hard solder layer (31).
