Photonetics TUNICS-PRI Tunable Laser Diode Source with options M & L

TUNICS-Purity provides the latest breakthrough in external cavity laser performance. It utilizes a new proprietary intra-cavity filtering scheme to fully eliminate background ASE noise and emit a pure single-mode laser line without any compromise to output power or wavelength stability. TUNICS-Purity models cover the S-, C- and L-band from 1465 nm to 1625 nm.

A new patented configuration yields an intra-cavity filtering of the background broadband ASE noise. The equivalent full width at half maximum (FWHM) of this filtering is as narrow as 0.15 nm which makes the residual ASE almost unmeasurable. TUNICS-Purity emits a pure high-power single-mode laser line, thus enabling direct spectral measurements of filters and multiplexers with an unsurpassed dynamic range. This avoids complex set-ups requiring an additional tracking filter or an optical spectrum analyzer, which often cause loss. TUNICS-Purity design utilises all the features of TUNICS-Plus:ultra-stable self-aligned cavity,active control of mode-hop-free operation, high output power,wide continuous tunability,multiple modulation possibilities and internal wavelength referencing. TUNICS-Purity is also the ideal instrument for an accurate testing of amplifier signal over noise ratio. TUNICS-Purity provides a pure ASE-noise-free operation with no compromise to other key features of state-of-the art tunable external-cavity laser-diodes.
