Abstract

With continuously increasing output power of fiber lasers, small volume, lightweight, high electro-optic efficiency fiber laser is needed. The weight of the semiconductor laser accounts for half of the weight of the entire fiber laser. Therefore lower weight high brightness high power diode laser pump source has become the inevitable trend of development. Lightweight need small volume, low density material. Copper and aluminum are commonly used shell materials. Copper has excellent heat dissipation which density is three times that of aluminum. Lightweight need to balance the contradiction between heat dissipation and weight. BWT designed a diode laser pump source which power ratio is 2.3W/g. The shell materials are mainly copper and aluminum. Using spatial beam combination, polarization beam combination, together with 3-dimensional space dense arrangement, lower weight diode was achieved.
