Spectral Linewidth 10kHz; Tuning range 38-60nm; Output Power 7-17dBm; In-operation Power Adjust 7dBM-MAX; In-operation Frequency Adjust +/- 12GHz The Pure Photonics tunable laser is founded on a volume-produced micro-ITLA tailored for the Telecom industry, guaranteeing top-notch performance, quality, and reliability. A telecom-grade variant with unaltered hardware and optimized firmware is available, alongside a sensor-grade option featuring optimized hardware and firmware with customizable features. These configurations allow for tailored adjustments in output power performance (up to 17 dBm for C-band and 16 dBm for L-band) and frequency range (up to 60 nm). Additionally, each version can be further augmented with available operating features such as modulation and fast tuning. The low-noise tunable lasers are available either standalone, with an evaluation board (PPEB700), or integrated into select models such as the PPCL500 (or PPCL600), PPCL550 (or PPCL700), PPCL560 (featuring a DB-9 interface), or CoBrite enclosure. The comprehensive Pure Photonics full-band tunable laser solution boasts an exceptionally narrow linewidth (~10 kHz), markedly reduced low-frequency AM and FM noise, and a variety of operating modes within this low-noise realm. Moreover, the product facilitates access to any desired frequency set-point within the tuning range (C-band, L-band, or optionally up to 60 nm), with output power adjustable from as low as 7 dBm to as high as 18 dBm.
