研制了一种定制光纤激光器作为生物医学光声断层成像的激励源。它基于定制绘制的大芯径光纤（200 μ m），可实现高脉冲能量（~ 10 mJ）。该系统可以提供可变脉冲持续时间（10 - 500 ns）和脉冲重复频率（100 Hz - 1 kHz），以及根据特定用户定义的序列的任意脉冲爆发。该系统结构紧凑，不需要外部水冷却。这一点，以及它所提供的输出时间特性的灵活性，将有助于光声成像在医学和生物学中的实际应用。
A custom fibre laser designed as an excitation source for biomedical photoacoustic tomography has been developed. It is based on a custom-drawn large core diameter fibre (200 µm) that enables high pulse energies (∼10 mJ) to be achieved. The system can provide variable pulse durations (10 - 500 ns) and pulse repetition frequencies (100 Hz - 1 kHz), as well as arbitrary pulse bursts according to specific user defined sequences. The system is also compact and does not require external water cooling. This, along with the flexibility in the temporal characteristics of its output that it offers, will aid the translation of photoacoustic imaging to practical application in medicine and biology.
