Highly Ho3+-doped silicate fiber for short fiber laser applications
Yin-Wen Lee;Yu-Cheng Chang;Yi-Chun Chen;Cheng-Hsien Yu;Ping-Han Tsai;Tzu-Ping Chuang;Han-Chun Chi

We report on the experimental demonstration of heavily Ho3+-doped silicate fiber laser with a gain per unit length of more than 1 dB/cm. A short 2058 nm Ho3+-doped silicate fiber laser has also been presented to confirm the high signal gain per unit length.

A Passively Q-switched Er-doped Fiber Laser Based on ZrSe2
Hsin-Ju Peng;Zhen-Ying Li;Shwu-Yun Tsay;Yao-Hui Chen;Ja-Hon Lin

The ZrSe2 platelets have been used as a saturable absorber to produce the Q-switched pulses from Er-doped fiber laser. The pulse repetition rate increases and pulse duration decreases as pump power increases and shows the highest pulse energy around 139 nJ at the highest pump power of 346 mW.

Shu-Ching LI
Generation and characterization of burst modes in passively mode-locked lasers with internal Fabry-Perot cavities

The generation of burst pulses in a multi-pass passively mode-locked laser is systematically explored. The intracavity mirrors with different thickness was exploited to serve as reflected Fabry-Perot (RFP) cavities in laser resonators.

Li-Yuan Yang
Two-stage Laser Amplifier with Maximum Output Energy
Tzu-Chih Liu;Li-Yuan Yang;Ming-Hsiung Wu;Yen-Chieh Huang

We built a two-stage laser amplifier system with a design to utilize full capacity of the power supply and maximize laser output energy. When seeded with a 0.05-mJ, sub-ns lase pulse at 1064 nm, amplifier can synchronously produce 15-mJ pulse energy from first stage and 120-mJ from second stage amplifier.

Compact efficient high-power triple-color Nd:YVO4 yellow-lime-green self-Raman lasers
Y.F. Chen;Yen Ying Pan;Y.C. Liu;C.M. Chen;J.Q. Hsiao;C.H. Tsou;H.C. Liang

We report a high-power compact efficient yellow-lime-green triple-color Nd:YVO4 self-Raman laser. The simultaneous three-color operation is accomplished by using three different LBO crystals. By tuning the temperature of each individual LBO crystal, the 588 nm, 559 nm and 532 nm output powers can be nearly concurrently up to 2.4 W.

High-power THz generation from KTP
Yan-Jou Lin;Ming-Hsiung Wu,;Chang-He Guo;Bao Dong To,;Yen-Chieh Huang

We report the detection of 2.26-μJ energy radiation at 5.65 THz from a KTP off-axis THz parametric oscillator with a 24-mJ pump energy and a 2-mJ Stokes energy. With a measured pulse width of 82.5 ps, the peak power of the generated far-IR radiation is 27.4 kW.

Nonlinear pulse compression of an Yb:KGW amplifier by a gas-filled multi-pass cell
An-Yuan Liang;Chia-Lun Tsai;Ming-Chang Chen;Shang-Da Yang

We have demonstrated pulse compression of an Yb:KGW amplifiers by a gas-filled multi-pass cell. The transform-limited pulse is reduced from 170 fs to 24 fs with a power throughput of 90%. The M2 values are 1.12 and 1.17 in x- and y- direction.

Electro-Optic Spectral Tuning in Multi-Wavelength Optical Parametric Oscillator Using Nonperiodically Poled Lithium Niobate
Tien-Dat Pham;Shue-Shan Lin;Lin-Ming Deng;Quan-Hsiang Tseng;Hung-Pin Chung;Wei-Kun Chang;Yen-Hung Chen

We report electro-optic (EO) spectral tuning of a multi-wavelength intracavity optical parametric oscillator (IOPO) based on a nonperiodically poled lithium niobate (NPPLN) constructed with a genetic algorithm. An EO spectral tuning rate of ~0.56 nm/(kV/mm) in this dual-signal NPPLN IOPO in telecom bands is achieved.
