| 摘 要： | 对脊形波导区和锥形区电极分离的980nm锥形激光器(简称电极分离的980nm锥形激光器)改变脊形波导区所加电流,测试激光器的P-I特性和光束质量因子,与脊形波导区和锥形区共用电极的980nm锥形激光器(简称电极共用的980nm锥形激光器)的测量参数进行对比.发现电极分离的980nm锥形激光器的P-I特性曲线比较光滑,没有明显的扭折.随着脊形波导区的电流逐渐超过150mA以后,器件的最大输出功率逐渐达到4.28W,与电极共用的980nm锥形激光器相同并趋于饱和,光束质量因子从3.79降到2.45(输出功率为1W).

| Abstract: | High-brightness tapered diode lasers emitting at 980nm with electrically separated ridge waveguide and tapered section were fabricated.The output power of the tapered section increases with the increase of the ridge waveguide current.An output power of 4.28W,which is the maximum output power with common contacting,is achieved at IRW=150mA.The power-current characteristics remain linear within the studied current range.When the output power of the tapered lasers is 1W,the beam propagation ratio decreases from 3.79 with common contacting to 2.45 with separated contacting. |

| Keywords: | tapered lasers 980nm separate contacting beam propagation ratio |
