Correction to: 3.5 ps burst mode pulses based on all‑normal dispersion harmonic mode‑locked

100-ps-pulse-duration, 100-J burst-mode laser for kHz-MHz flow diagnostics.

A high-speed, master-oscillator power-amplifier burst-mode laser with ∼100  ps pulse duration is demonstrated with output energy up to 110 J per burst at 1064 nm and second-harmonic conversion efficiency up to 67% in a KD*P crystal. The output energy is distributed across 100 to 10,000 sequential laser pulses, with 10 kHz to 1 MHz repetition rate, respectively, over 10 ms burst duration. The pe...

Burst Mode Q:switched Laser Pulses for Plasma Excitation in LIBS Analysis

Deterministic approach to polarization mode dispersion

Polarization Mode Dispersion (PMD) is considered to be one of the most serious obstacles in the high speed optical telecommunication systems. This thesis focuses on a deterministic approach to both compensation and emulation of PMD. Most PMD compensation schemes in the literature rely on feedback loops to search for the optimum control parameters in the compensator. These schemes often suffer f...

Frequency detuning properties of EDFL pulses generated by harmonic mode-locking and regenerative amplification: a comparison

We compare the frequency detuning properties of optical pulses generated from erbium-doped fiber lasers (EDFL's) by using harmonic mode-locking and regenerative amplification techniques. The frequency detuning range of regeneratively amplified pulse (17.78 kHz) is wider than that of harmonic mode-locked pulses (7 kHz). The regeneratively amplidied EDFL pulse has a smaller pulsewidth (22ps), a h...

Nonlinear chirp of dispersion-managed return-to-zero pulses.

Applying variational methods, we derive a reduced system of equations from the nonlocal equation that governs the average dynamics in dispersion-managed systems. These equations, which apply for any type of return-to-zero pulse, describe the stroboscopic evolution of the pulse parameters and bypass the fast variations inside each dispersion map. In the limit of large map strength we integrate t...
