In this research, Amplified Spontaneous Emission (ASE) spectrum characteristics for a highly Yb3+ doped glass fiber with different pump powers and pump wavelengths are scrutinized. ASE spectral profil...
A multiwavelength fiber ring laser that is based on an S-band erbium-doped fiber amplifier (EDFA) and a semiconductor optical amplifier (SOA) is developed. An optical switch is used to switch the mult...
We demonstrated an Erbium-doped picosecond fiber laser mode locked by carbon nanotube in N-methyl-2-pryrrolidone solvent in an in-fiber micro-channel.
We demonstrated an Erbium-doped picosecond fiber laser mode locked by carbon nanotube in N-methyl-2-pryrrolidone solvent in an in-fiber micro-channel.
I will overview our recent results on ultra-long lasers and will discuss the concept of a fiber laser with an open cavity that operates using random distributed feedback provided by Rayleigh scatterin...
Yb-Fiber Laser Frequency Combs     Yb-Fiber  Laser Frequency  Combs       2015/6/9
Significant progress in Yb-fiber laser based frequency combs over the last few years resulted in sub-Hz relative comb-tooth linewidths, average powers over 60W and GHz comb spacings enabling novel app...
A high-power hybrid Brillouin/ytterbium fiber laser is demonstrated with an output power of 1 W. The laser operates in the single-frequency regime with an optical signal-to-noise ratio greater than 55...
We present a new method to induce low loss tunable birefringent phase shifts in fiber Bragg grating by applying mechanical stresses at precise locations along the FBG with a specially designed shape m...
We experimentally demonstrate a tunable photonic microwave notch filter by employing two fiber Bragg grating-based dual wavelength laser. Based on the bending technique along the gratings, notch frequ...
We observed laser oscillation for a multimode Nd-doped fiber laser with D-shaped cladding under quasi-solar-pumping simulated by an intense halogen lamp with a color temperature of 5,600 Kelvin. The f...
We have developed a novel optical fiber ring laser using a semiconductor optical amplifier (SOA) as the gain medium, and taking advantage of polarization anisotropy of its gain. Since the frequency di...
High-power pulse fiber lasers (HPPFLs) using Yb-doped double-clad fiber for industrial applications are evolved as two types including Seed LD-based Master-Oscillator Power-Amplifier (Seed-LD-MOPA) an...
We have experimentally demonstrated an efficient all-fiber passively Q-switched Yb-doped fiber laser with Samarium doped fiber as a saturable absorber. Average output power of 3.4 W at a repetit...
We present an optical frequency synthesizer based on two DFB lasers that can be selectively injection-locked to a desired single mode among the femtosecond fiber laser comb components.
We demonstrate passive filtering of laser relative intensity noise by active frequency locking a laser to a cavity, thereby producing a shot-noise limited optical source suitable for quantum cryptogra...
