| Technical Description | 1.Technology based on noise-like pulsed (NLP) fiber laser and supercontinuum generation (multiple patents). 2.Tunable and can generate watt level average power with bandwidths of 10-100 nm. The output energy of the NLP laser can be scaled to tens of microjoules by multi-stage amplification. 3.Excited by NLPs, a 10-m length of Ge-doped single-mode fiber can generate a supercontinuum with a flat spectrum and FWHM of 1030–1470 nm. 4.Exciting a length of photonic crystal fiber, a supercontinuum covering the visible and near infrared band (440-2200nm) can be generated. 5.Using this source for optical coherence tomography (OCT), sectional resolution is as high as 2.3 micron. 6.Multi-frame averaged OCT images obtained with this source exhibit much better image quality than competitive sources. 7.Potential applications in white-light interferometry, lidar, LIBS（Laser Induced Breakdown Spectroscopy）, fiber sensing, optical network testing, machining and material processing. |
