摘要	A semiconductor laser device has a laser-oscillating optical waveguide (1) composed of a control region (2) which functions to absorb light and main regions (3) which function to oscillate laser light, said control region (2) being positioned in the centre portion of said optical waveguide (1) and said main regions (3) being positioned on both ends of said control region (2), wherein said laser device further comprises a shunting means (Rg) by which the ratio of the current Ig flowing to said control region to the total current It injected into said laser device is set to meet the inequality (1):wherein Lg is the length of said control region and Lt is the length of said optical waveguide.
其他摘要	半导体激光装置具有激光振荡光波导（1），其由用于吸收光的控制区域（2）和用于振荡激光的主区域（3）组成，所述控制区域（2）位于所述光波导（1）的中心部分和所述主区域（3）位于所述控制区域（2）的两端，其中所述激光装置还包括分流装置（Rg），其中电流Ig流动的比例将所述控制区域注入到所述激光器件中的总电流被设定为满足不等式（1）：其中Lg是所述控制区域的长度，Lt是所述光波导的长度。
