我们提出了一个线性激光谐振腔，它包括半导体光放大器和扫描滤波器，用于高重复频率、宽波长、单向扫描。该激光器工作在高达115 kHz的重复频率，并展示了> 30 mW的调谐速度无关的功率。我们应用这种激光器，使超高速光学频域成像的动态激光消融生物组织。成像系统在8.7 μ s内采集单次纵向扫描（A线），并以每秒200帧的速率采集包括575条A线的完整横截面图像。(c)2006年，美国物理学会。
We demonstrate a linear laser resonator incorporating a semiconductor optical amplifier and scanning filter for high repetition rate, broad wavelength, unidirectional scanning. The laser operates at up to 115 kHz repetition rates and demonstrates a tuning-speed-independent power of > 30 mW. We apply this laser to enable ultrahigh-speed optical frequency domain imaging of the dynamics of laser ablation of biological tissue. The imaging system acquires single longitudinal scans (A-lines) in 8.7 mu s and complete cross-sectional images comprising 575 A-lines at a rate of 200 frames per second.
