摘要	A 980 nm bottom-emitting vertical-cavity surface-emitting laser linear array with high power density and a good beam property of Gaussian far-field distribution is reported. This array is composed of five linearly arranged elements with a 200 m diameter one at the center, the other two 150 m and 100 m diameter ones at both sides of the center with center to center spacing of 300 m and 250 m, respectively. A power of 880 mW at a current of 4 A and a corresponding power density of up to 1 kW/cm2 is obtained. The temperature dependent characteristics of the linear array are investigated. The thermal interaction between the individual elements of the VCSEL linear array is smaller due to its optimized element size and device spacing, which make it more suitable for high power applications. A peak power of over 20 W has been achieved in pulsed operation with a 60 ns pulse length and a repetition frequency of 1 kHz. 2009 Chinese Institute of Electronics.
