Reducing the Impact of Intrachannel Nonlinearities By Pulse-Width Optimisation in Multi-level Phase-Shift-Keyed Transmission
Intrachannel Nonlinearities Pulse-Width Optimisation Multi-level Phase-Shift-Keyed Transmission

2015/7/20
We investigate the reduction in the duty-cycle for M-phase-shift-keyed transmission, demonstrating performance improvement in the range of 2-8 dB in nonlinear threshold (NLT) due to intrachannel-four ...
Performance of Parametric Wavelength Exchange for Narrow Pulse Width Return-to-Zero Signal
Parametric Wavelength Exchange Narrow Pulse Return-to-Zero Signal

2015/7/14
We demonstrate the parametric wavelength exchange for 10-Gb/s RZ and NRZ signals. The narrow pulse width of the exchanged RZ signal indicates that CW or quasi-CW pumps are capable of handling with ult...
A 12.4 W Ti:sapphire Based Regenerative Amplifier System with 200 fs Pulse Width at 50 kHz Repetition Rate
Femtosecond Amplifier Ti:sapphire

2009/6/1
We have developed a cryogenically cooled Ti:sapphire regenerative amplifier at the repetition rate of up to 100 kHz which was pumped by the intracavity SHG pulses of Yb:YAG thin disk laser. An electro...
Low threshold narrow pulse width eye-safe intracavity optical parametric oscillator at 1573 nm
Optical parametric oscillator Eye-safe laser Diode-end-pump Q-switched
