Study of high power CBC fiber laser systems with non-equal splitting ratio beam-splitters
Results in Optics, 2023 High power coherent beam combination (CBC) with non-equal splitting ratio beam splitters (BS) is studied. A BS-based two-channel CBC laser system has been built, and experiments with 50:50 BS and 30:70 BS has been carried.

Impact of atmospheric turbulence on coherent beam combining for laser weapon systems
Defence Technology, 2021 The performance of a laser weapon system based on coherent beam combining (CBC) depends on its propagation properties in the atmosphere. In this study, an analytical model based on partial coherent beam combining (PCBC) for assumed coherence coefficients

Design of a 36-W fiber-coupled green laser diode by Zemax
Results in Physics, 2018 We propose a design of a 36 W fiber-coupled green diode laser based on TO-Can packaged emitters using Zemax. This is achieved by beam collimation, spatial beam combining, polarized beam combining and fiber coupling.

Spectral Bandwidth Narrowing of High Brightness Spectral Beam Combining Diode Laser
IEEE Photonics Journal, 2017 We introduce a 5x demagnifying telescope system into an external cavity spectral beam combining and realize a narrow spectrum diode laser combining output by using a nine-emitter 970 nm diode laser mini-bar. With an external feedback mirror of 10%

Mitigating parametric instabilities in plasmas by sunlight-like lasers
Matter and Radiation at Extremes, 2021 Sunlight-like lasers that have a continuous broad frequency spectrum, random phase spectrum, and random polarization are formulated theoretically. With a sunlight-like laser beam consisting of a sequence of temporal speckles, the resonant three-wave ...

Surface wettability control on zircaloy-4 by nanosecond Nd:YAG laser with beam homogenizer
AIP Advances, 2022 We introduce the laser-induced surface processing (LISP) method that imparts hydrophilicity and hydrophobicity using a Nd:YAG nanosecond laser, especially the high-fluence (HF) condition for fast processing and the low-fluence (LF) condition to control ...
