ASE 2 µm Broadband Laser Source

SKU: TASE

The TASE series of Thulium-Doped (Tm) Fiber ASE Benchtop is an amplified spontaneous emission (ASE) source operating around 1900 nm that provides turnkey operation and singlemode broadband emission with low coherence and randomized polarization, making it ideal for high-precision measurement applications. Each TASE fiber laser is constructed using a thulium-doped fiber as the gain medium and pumped by a single-mode laser. The TASE has broad bandwidth, and the output power is precision stabilized by a feedback controller, making it a reliable benchtop laboratory instrument. The laser output is accessible via a fiber connector bulkhead compatible with 2.0 mm narrow key FC/APC connectors. An integrated isolator at the output minimizes the impact of back reflections on the laser cavity. It has a front power control knob and a USB computer interface. An emission switch adds safety. The typical optical emission of the ASE1900 has an 1870 nm center wavelength and a 100 nm spectral width measured 20 dB below the peak value. When the current driving the laser diode pump source is set to its maximum, the typical ASE output power measured over the entire emission band is 50 mW. The ASE source can be customized to have slightly shorter or longer center wavelengths upon request. An interlock pin is installed. The ASE source includes a universal power supply, allowing operation over 100 to 240 VAC without the need to select the line voltage. This unit is supplied with a region-specific power cord. The fuse access is conveniently located on the back panel.
