Interference-filter-tuned, alignment-stabilized, semiconductor external-cavity laser

Abstract

We compared the angular alignment tolerance and the tuning range of a novel interference-filter-tuned semiconductor external-cavity laser based on a degenerate resonator with characteristics similar to those of a conventional grating-tuned external-cavity laser using a 1300-nm In GaAsP Fabry-Perot laser with an antireflection-coated facet as the gain medium. The interference-filter cavity had a 260-fold greater alignment tolerance (+/-26 versus +/-0.1 mrad) and nearly the same tuning range (90 versus 110 nm) as the grating-tuned cavity.

Interference-filter-stabilized external-cavity diode lasers

“…Displacements of other optical elements can be transformed into one of these. The computation of F turns out to be independent of the number of lenses in the cavity, and can be simplified by calculating the overlap integral F = R −1 | E * rei E rer dxdy| 2 at the position z = z re of the reflective element [4]. Here E rei and E rer are respectively the incident and reflected electric fields on the out-coupler.…”

“…Более предпочтительна для использования в БОРЧ схема, предложенная в [43] и изображен-ная на рис. 3, где в качестве отражателя использу-ется отражатель типа «кошачий глаз», а для дискри-минации длин волн -интерференционный фильтр.…”

Narrow bandwidth interference filter-stabilized diode laser systems for the manipulation of neutral atoms

“…The advantage of this design is that the wavelength discrimination and the optical feedback are performed by two independent elements, the interference filter and the out-coupler [7]. In combination with the linear design of the setup, the interference filter-stabilized configuration offers a higher stability and tunability compared to the Littrow design [6,9]. Furthermore, the wavelength dependent spatial displacement of the out-coupled beam is reduced compared to grating-stabilized setups.…”

“…In this article, we compare four different laser systems, based on a narrowband high transmission interference filter, as presented in [6] and [7]. The laser designs offer an improved stability and tunability compared to grating-based setups combined with convincing spectral properties.…”
