New wavelength for the popular miniTA and miniECL laser diode family: 670 nm

TOPTICA EAGLEYARD is starting off the new year with great news: the long awaited 670 nm wavelength finally becomes available as new addition to the miniTA and miniECL product families. Both innovative products were first launched in 2022 and have extended its wavelengths step by step offering up to six standardized wavelengths per product now.

The new 670 nm miniTA comes with the same great characteristics as the other wavelengths such as integrated thermal management and beam collimation all in an optimized hermetically sealed butterfly package with 14 thicker pins for ideal power supply. The “plug and play” with fiber pigtail seed lasers are a true game-changer especially in applications such as spectroscopy, quantum technologies and atomic clocks.

Measurements show the high optical single mode power up to 1 W and high ASE suppression. The miniTA is available with 1 W @ 670 nm 1.5 W @ 765 nm (covering 767 & 770 nm), 3 W @ 780 nm, 2 W @ 795 nm, 2 W @ 852 nm and 2.5 W @ 895 nm. The evaluation board that is very intuitive to use, can be ordered together with the miniTA and helps customers with faster testing and preparation.

The new 670 nm miniECL comes with 40 mW (Li D1 & D2 line) and is an important addition to all other available wavelengths at 80 mW @ 770 nm (K D1 line), @ 780 nm (Rb D2 line), @ 852 nm (Cs D2 line), @ 895 nm (Cs D1 line).  This single frequency laser diode has a super fine linewidth of typical 100 kHz. Moreover, wavelengths between 650 – 1100 nm are customizable upon request, opening more freedom across the spectrum. The integrated beam collimation, thermoelectric cooler and thermistor enable an easy usage. Thanks to the hermetically sealed package, the miniECL is very robust and enables very small linewidth for precise results. The miniECL is frequently used in spectroscopy, QT, metrology, atomic clock and life science.
