Single Frequency High Peak Power Fiber Lasers for Lidar and Micromachining
Shibin Jiang
We successfully developed a series of single frequency fiber lasers with greater
than 1mJ pulse energy at wavelength of 1micron, 1.55micron, and 2micron, which represent
the highest pulse energy of such types of lasers in the world to the best of our knowledge.
Their applications for Lidar and micromachining process will be presented.

Generation of sub-megawatt-peak-power femtosecond pulses from a single 24MHz Cr:forsterite oscillator for video-rate three-photon microscopy
Hao-Hsuan Hung;Lu-Ting Chou;Dong-Lin Zhong;Chao-Hsu Wen;Chao-Jin Jan;Zi-Ping Chen;Shih-Hsuan Chia
We have obtained sub-megawatt-peak-power femtosecond pulses around 1.3µm driven by a 24-MHz Cr:forsterite oscillator and a piece of optical fiber, by carefully controlling the intracavity dispersion and nonlinear fiber-optic conversion. The compactness of our demonstration with a 24-MHz repetition rate will enable video-rate deep-tissue observation via GFP-based three-photon fluorescence microscopy.

Volume holographic light sheet microscopy using Bessel beams for live imaging of Caenorhabditis elegans
Yu-Chun Chen;Ting-Yu Hsieh;Sunil Vyas;Kuang-Yuh Huang;Yuan Luo
To image volumetric biological samples optical sectioning capability is required. Here, we propose a compact Bessel light sheet fluorescence microscope (LSFM) using volume holographic grating (VHG) for real time high resolution volumetric imaging of Caenorhabditis elegans (C. elegans). A photopolymer (PQ-PMMA) based VHG is designed to generate Bessel beam.

A compact femtosecond fiber source tunable between 740-1236 nm for wide two-photon fluorescence microscopy applications
Lu-Ting Chou;Yu-Cheng Liu;Dong-lin Zhong;Ming-Che Chan;Shih-Hsuan Chia
By controlling the fiber-optic nonlinearity, we have demonstrated and characterized a compact nJ-level femtosecond fiber source widely-tunable between 740-1236 nm, covering the most two-photon-excitation wavelengths for deep-tissue microscopy applications. We believe the robustness and applicability of this source have made it a promising substitution of Ti:sapphire-based systems for biomedical imaging.

Sub-terahertz Photoacoustic Pulse Generation using Platinum Nanofilms
Chi-Kuang Sun;Chih-Yuan Tsai
Platinum is strong electron-phonon-coupling metal and is expected to provide ultrahigh frequency photoacoustic pulse. Here we report our study on the sub-terahertz (THz) photoacoustic pulse generation using platinum nanofilms. With an average thickness of 0.9 nm, 0.38 THz central frequency photoacoustic pulse was successfully measured after femtosecond optical excitation.
