We present a stable broadband supereontinuum source and a time-stretehed detection scheme for the real-time imaging system. The proposed source and detection scheme will allow the imaging system to track the evolution of the pulses when they interact with the target.
A new design hybrid passive harmonic mode-locked fiber laser with integrated Faraday rotator and SESAM in sigma configuration is built. The integrated SESAM Faraday rotator acts as the mode-locker. A MZ modulator provides amplitude modulation to stabilize and order optical pulses. Stable evenly spaced femtosecond optical pulses are generated.
We demonstrate a 2 µm passive mode-locked fiber laser. A single-wall carbon nanotube (SWCNT) is used as saturable absorber. Thulium-doped fiber (TDF) is used as the gain medium. The output wavelength is grating stabilized to 1998.85 nm by a high reflective (HR) fiber Bragg grating (FBG) together with a two by two coupler. A 8.22 MHz fundamental mode-locked pulsed laser with output signal power of...
Generation of super-continuum by using 5 m ultra-high NA silica optical fiber (UHNA3) with core diameter 1.8 µm and mode-field diameter (MFD) ∼2.6µm is compared with Photonic Crystal Fiber (PCF). A 1064 nm gained switched pico-second semiconductor pulsed laser source is used to study the performance of supercontinuum generation and the amplified signal is coupled by direct splicing with UHNA3 fiber...
We construct a high gain high output power 1310 nm hybrid fiber amplifier, which can be use in telecommunication. It is a compact design combining a semiconductor optical amplifier (SOA) and a discrete Raman amplifier. It is hard to construct such amplifier by either using a SOA or a discrete Raman fiber amplifier with compact design. The amplifier is designed for a 1310 nm small signal input providing...
