Simultaneous multi-peak yellow-orange laser based on monolithic Nonlinear Photonic Crystals(NPCs) was demonstrated. The temperature bandwidth(FWHM) of our design could reach near ten degree and slope efficiency was over 8.5%. Furthermore, the number of peaks could be controlled by modulating the periodicities of the OPO and SHG/SFG part.

Cang-He Guo Tunable THz parametric amplifier seeded by strongly focused Stokes wave
Cang-He Guo;Yen-Chieh Huang

We demonstrated the THz wavelength tuning between 5.43 and 6.1 THz without aligning. By strongly focusing the seed laser, the optical path can satisfy the momentum conservation of non-collinear phase matching in a THz parametric amplifier. The measured maximum output THz energy was ~2.26 μJ at 5.7 THz.

Chun-Yu Cho Mid-IR continuous-wave intracavity optical parametric oscillator with optically pumped semiconductor laser
Chun-Yu Cho

Utilizing intracavity optical parametric oscillator (OPO) is an efficient method for generating continuous-wave mid-IR laser. However, when the solid-state gain medium was utilized as the parent pumped near-IR source, serious self-pulsing well be observed due to the strong coupling between relaxation oscillation and OPO depletion. In this work, optically pumped semiconductor laser is employed to overcome the self-pulsing issue. Theoretically analysis is also performed to verify the experimental result.

Kun-You Huang Extraordinary Response of VCSEL on RIN Spectrum
Kun-You Huang;Jui-Hung Weng;Gong-Ru Lin

The relative intensity noise (RIN) spectrum is a parameter that can be used to choose a vertical-cavity surface-emitting laser (VCSEL) for transmission. The RIN measurement is from 100Mz to 20GHz. However, this range may ignore the frequency response higher than 20GHz, and affect the performance of VCSEL.
