Liquid crystalline organic photonic crystals for direct all-optical compression and modulation of ultrafast laser pulses
Iam-Choon Khoo

We report successful fabrication of well aligned cholesteric liquid crystal cells of record-setting thickness, and critically examine the role played by band-edge dispersion and enhanced ultrafast electronic optical nonlinearity in recent successful observations of direct femtosecond laser pulse modulations and group velocity slow-down.

Tze-An Liu 100 GHz Passively Mode-Locked Fiber Laser Realized by Nonlinear Fused-Quartz Micro-Resonator
Tze-An Liu;Yi-Chen Chuang;Wei-Jo Ting;Yuh-Chuan Cheng;Po-Er Hsu;Jin-Long Peng;Chao-Hua Wen

This paper describes the development of a 100 GHz high repetition rate mode-locked fiber laser including a fused-quartz micro-resonator. More than 10 comb lines were generated by adjusting the dual fiber coupling position and the polarization controller. Results demonstrated the mode-locking pulse-width of 1.2 ps as well.

CHI-MENG LU Electro-Optic Controlled, Highly Spectrum Narrowed Multiline Intracavity Optical Parametric Oscillators
CHI-MENG LU;Hung-Pin Chung;Wei-Kun Chang;Yen-You Chou;Reinhard Geiss;Shang-Da Yang;Thomas Pertsch;Yen-Hung Chen

An electro-optically (EO) spectrum narrowed, multiline intracavity optical parametric oscillator (OPO) is built based on a novel aperiodically poled lithium niobate device. The power spectral density of this EO controlled OPO has been enhanced by a factor of ~7.8 in contrast to the system operated in passive mode.

Chia-Lun Tsai 1-kHz, 3.3-mJ, 88-fs pulses at 1.55 μm by optical parametric chirp pulse amplifier
Chia-Lun Tsai;Yi-Hsun Tseng;Ming-Wei Lin;Shang-Da Yang;Ming-Chang Chen

We demonstrated 1-kHz, 3.3-mJ, 88-fs pulses at 1.55 μm by an optical parametric chirp pulse amplifier. For pursuing shorter pulses, we also demonstrate spectral broadening method which supports 18 fs (3.5-cycle) transform-limited pulses. This powerful laser system is essential for high order harmonic generation – coherent soft x-ray generation.

Ying Kuan Ko Development of Ultrafast Near-Ultraviolet and Deep-Ultraviolet Laser Pulses
Ying Kuan Ko;Atsushi Yabushita;Bing Xue;Takayoshi Kobayashi

For application of ultrafast time-resolved spectroscopy, we have developed the broadband sub-10 fs ultrafast laser pulses in near-ultraviolet (NUV) and deep-ultraviolet (DUV) range by using self-phase modulation (SPM) and broadband chirped-pulse four-wave mixing (BCP-FWM) process in noble gases filled hollow fiber.
