TFL2000 Compact 2 µm Band Fiber Laser


The TFL-2000 is a compact, turn-key 2 µm band infrared fibre laser. Based on the highly efficient, thulium fibre technology, the TFL-2000 outputs up to 1, 2 or 5 W of continuous power from a single-mode fibre, delivering reliable infrared light to wherever it is needed. Polarised or unpolarised outputs are available depending on the user’s applications. Standard fibre output with free space output optional.

The TFL-2000 comes with built-in wireless remote control of all laser parameters via an app, giving you the freedom to easily control the laser from anywhere in the lab. The TFL-2000 is a simple, turn-key solution that can be readily incorporated into any experiment requiring 2 µm band light.
