Advances in narrow linewidth diode lasers [PDF]
Science China Information Sciences, 2019 The era of smart travel has arrived, and the need for high precision lidar detection technology is increasing. With the advantages of high resolution, a strong anti-active jamming ability, small volume, light weight, and low cost, new solid-state lidars can meet the requirements of intelligent cars in the future.

Conference on Lasers and Electro-Optics, 2022
By exploiting Fano resonances, a microscopic laser with a linewidth >20 times smaller than previous microscopic lasers is experimentally demonstrated. We also show that the linewidth can be further improved by engineering the Fano lineshape.

Hybrid integrated narrow-linewidth semiconductor lasers
Applied Optics, 2023Integrated narrow-linewidth lasers are the key devices in compact coherent optical systems of metrology, sensing, and optical microwave generation. Here, we demonstrate a hybrid integrated laser based on an optical negative feedback scheme.

Narrow-linewidth unstable resonator
Optics Letters, 1988We describe the use of an asymmetric feedback ring in an unstable resonator to obtain arbitrarily narrow-linewidth radiation across the full available aperture. We demonstrate its use with an electric-discharge XeCl laser to produce single-line radiation with a linewidth of 0.15 cm−1.

Narrow linewidth unstable resonators
Annual Meeting Optical Society of America, 1988We have previously demonstrated that a feedback ring in an unstable resonator can be useful in providing narrow bandwidth radiation across the full available aperture of the resonator. In this configuration the light traveling in the forward direction in the ring passes through frequency-narrowing etalons while it is collimated and is then coupled back

Narrow-Linewidth Microlasers on Silicon
Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2007After reviewing several laser sources based on high-Q microtoroid lasers, the recent observation of fundamental linewidths as narrow as 4 Hz in microtoroid lasers will be described. Inverse-power (Schawlow-Townes) broadening is observed.

Progress and trend of narrow-linewidth lasers
Science China Technological Sciences, 2013High frequency stability, narrow-linewidth lasers have been long dreamed of since the invention of the laser. They have recently developed dramatically due to the advent of optical clocks. State-of-the-art narrow-linewidth lasers have been constructed by using the Pound-Drever-Hall (PDH) technique to lock the laser frequencies to the resonance of ultra-

Narrow-Linewidth Lasers on a Silicon Chip
2014Diode-pumped distributed-feedback (DFB) channel waveguide lasers were demonstrated in Er3+-doped and Yb3+-doped Al2O3 on standard thermally ox-idized silicon substrates. Uniform surface-relief Bragg gratings were patterned by laser-interference lithography and etched into the SiO2 top cladding. The maxi-mum grating reflectivity exceeded 99%. Monolithic
