Toptica eagleyard’s Mini-ECL miniature external cavity laser is a single frequency laser diode with a super fine linewidth of typical 200 kHz and a collimated output. Stable performance is ensured by the integrated cavity in the hermetically sealed standard butterfly package with integrated temperature control and no moving parts. Moreover, wavelengths between 650 – 1100 nm are customizable upon request, opening more freedom across the spectrum. The standard product at 780 nm will mainly be used for spectroscopy (Rb D2 line), metrology and atomic clocks.

The advantages of the Mini-ECL become very obvious when looking at the reduced complexity based on the integration of the cavity. Due to the ease of use, the robustness of the package and therefore scalability, not only research applications will benefit from this innovation but commercial and industry requirements are more easily fulfilled than with already available solutions. This will lead to outstanding results and applications along the value chain.

Mini-ECL also serves as a perfect seeder for Toptica eagleyard's TPA series of tapered amplifiers, resulting in a MOPA system with up to 3 W single mode poutput power and a brilliant frequency stability inherited from the seeder.
