Sub-kHz single-frequency pulsed semiconductor laser based on NPRO injection locking
Chunzhao Ma, Wenxun Li, Weitong Fan +6
We report a single-frequency, narrow-linewidth semiconductor pulsed laser based on pump current modulation and optical injection locking technique. A monolithic non-planar ring osc…
Comprehensive Investigation of Fundamental Mode Profiles in Monolithic Nonplanar Ring Oscillators
Weitong Fan, Chunzhao Ma, Wenxun Li +5
Nonplanar ring oscillators (NPROs) are building blocks for high-performance single-frequency lasers and ring-laser gyroscopes that have profoundly improved the state-of-the-art las…
Temperature-insensitive fused-tapered fiber couplers based on negative thermal expansion material coating
Ze-Long Huang, Jie Xu, Jue Li +6
A new method based on negative thermal expansion material coating is proposed to realize temperature insensitive fiber coupler. By coating a layer of modified epoxy resin with a ne…
Frequency-shifted laser feedback interferometry in non-planar ring oscillators
Rong Zhu, Xuezhen Gong, Wenxun Li +7
Laser feedback interferometry (LFI) has a wide range of applications such as displacement, distance and velocity measurements. LFI has been realized in many types of lasers but has…
