An injection-locked 674 nm laser for Strontium-88 ion trapping
… processing. The qubit transition to a metastable energy state can be stimulated by a laser at a frequency of 444.779044 THz. A laser beam with higher intensity causes more rapid transitions between quantum states, and thus allows more computational operations within the coherence time of …

High power pulse UV source development and its applications
Laser filament provides scientists a powerful tool to promote and guide lightning discharge. An ultraviolet (UV) laser provides unique advantages due to a low threshold of filament formation as well as long propagation distance. However, a major bottleneck in conducting these experiments is the …

New techniques for multiple wavelength fiber laser generation based on edfa and tdfa
Multiple wavelength fiber laser (MWFL) can be a potential source for microwave generation as the conventional microwave generator have several issues in generating high frequency. In order to be such source, the MWFL must have the following criterion; a great number of comb lines, a compact design, …

Ultra-Narrow Laser Linewidth Measurement
… Recently, less than 1kHz linewidth fiber lasers have been commercialized. But even the manufacturers face a challenge on accurately measuring the linewidth of such lasers. There is a need to develop more accurate methods to characterize ultra-narrow laser linewidth and frequency noises. …

Towards Advanced Photonic Integrated Systems Through Electronic-Assisted Design
… design process. Second, a miniature laser wavelength stabilization system is demonstrated where the wavelength of a semiconductor laser (SCL) is locked to an RF frequency through a dispersive opto-electronic oscilla- tor (OEO). An order of magnitude reduction in the laser wavelength …

Thulium-doped fibre laser in the 2 μm wavelength region for gas sensing
… Thulium is widely studied for generating lasers at wavelength near 2 μm. For decades, tuneable continuous wave narrow line-width sources in this wavelength region have been proved to be very useful as spectroscopic tools for trace gas detection. Semiconductor lasers are often not readily …
