Collimation of High Fill Factor Diode Laser Slow Axis Beam

Spectral characteristics optimization of high power semiconductor laser diodes by adjusting the reflectivity of the cavity surface coating film

“…In order to achieve the effect of collimating the beam, several study designs have been conducted 9,10,11 . Consequently, many techniques have been employed to enhance the beam quality of semiconductor lasers 12,13 . Utilizing a fiber fragment with a localized numerical aperture as a microcylindrical lens presents a straightforward and cost-effective approach for achieving collimation of the fast-axis beam in semiconductor lasers.…”
