针对激光在生物神经科学研究中的应用,设计出了一种可遥控的脉冲激光器。这里介绍了以ZigBee为通信模块的脉冲源,具有集成度高、便携性强、体积小、成本低、工作稳定等优点。采用单片机为控制中心,利用相应的C语言程序,实现了电流脉冲宽度和脉冲频率的调节。该脉冲源用于驱动全固态半导体激光器,实现了距离为300米的遥控可调节脉冲,并由FC/PC光纤耦合输出。同时加入了恒温控制,保证了激光器的输出功率的稳定性,有效地延长了其使用寿命。该器件依托ZigBee自有的自组网技术,有着很好的应用前景。
In view of the application of laser in biological neuroscience research, a remote laser pulse generator is designed. Here introduced the pulse source for ZigBee communication module, with high integration, portability, small size, low cost, work stability and so on. SCM as a control center, the use of the corresponding C language program to achieve the current pulse width and pulse frequency adjustment. This pulsed source is used to drive all-solid-state semiconductor lasers and enables the remote control of adjustable pulses at a distance of 300 meters and is coupled out of the FC / PC fiber. At the same time joined the constant temperature control, to ensure the stability of the laser output power, effectively extending its service life. The device relies on ZigBee own ad hoc network technology, has a very good application prospects.
