Description

一种半导体激光驱动电源系统 技术领域
本发明公开了一种半导体激光驱动电源系统，具体为半导体激光驱动技术领域。
背景技术
随着科学技术的飞速发展，半导体激光器技术已深入到国民经济和国防建设的各个领域。半导体激光器具有其它激光器无法比拟的特性，比如：常见的激光器如He-Ne激光器，采用高压激发(约1500V)，而半导体激光器采用3～5V的低电压激发，相比之下，半导体激光器的激励方式较为安全，并且效率比普通激光器高数十倍；在一些测量仪器中，选用半导体激光器照明，能满足单色性好，相干性好，光束准直，精度高等要求，在远距离通讯、激光雷达、数字信号的存储和恢复、激光测距、机器人、全息应用、医学诊断等方面都有广泛的应用。但半导体激光器对工作条件要求苛刻，在不适当的工作或存放条件下，会造成性能的急剧恶化乃至失效。所以，使激光器正常工作的激光器驱动电源就显得尤为重要。因而在实际应用中对激光器驱动器的性能有着很高的要求。半导体激光器(LD)具有体积小、重量轻、转换效率高、工作寿命长等优点，在工业、军事、医疗等领域得到了广泛应用。LD是以电流注入作为激励方式的一种激光器，其使用寿命、工作特性在很大程度上取决于所用驱动电源的性能好坏。半导体激光器本身的性质决定其抗浪涌冲击能力差，这就要求驱动电源的稳定度高，浪涌冲击小，因此驱动电源中需要各种保护电路以满足实际要求。通常用慢启动电路、TVS(瞬态抑制器)吸收电路、限流电路等来防止浪涌冲击及电流过大。但大功率半导体激光器的工作电流较大，并且半导体激光器比较脆弱，传统的慢启动电路、TVS吸收电路不能很好地满足实际要求。
现有的半导体激光在驱动时大多采用一组电源模块，当需要对激光器参数进行修改时，就必须要启动激光器电源，并断开激光器开关，安全系数低，操作复杂。

为实现上述目的，本发明提供如下技术方案：一种半导体激光驱动电源系统，包括单片机控制模块，所述单片机控制模块的传输端口电性连接有工控机，所述工控机的电源接口电性连接有第二电源模块，所述第二电源模块的线路上设置有第二电源开关模块，所述工控机的电源接口电性连接有第一电源模块，所述第一电源模块的线路上设置有第一电源开关模块，所述单片机控制模块的传输端口电性连接有LD驱动模块，所述LD驱动模块的电源接口与第一电源模块电性连接，所述工控机的电源接口与第一电源模块电性连接，所述单片机控制模块的输出端口电性连接有散热风扇，所述单片机控制模块的输入端口电性连接有传感器模块，所述单片机控制模块的输入端口电性连接有操作控制模块。
