The Koheras AdjustiK™ E15 is a turn-key single frequency DFB fiber laser
system with active wavelength control and wide-range thermal wavelength
tuning. The laser comes with a fast piezo-electric tuning capability, where
the laser wavelength can be modulated externally at kHz modulation bandwidth to lock it to a stable reference.
This E15 benchtop system is based on our industry-leading BasiK™ OEM
laser modules and comes with integrated driver electronics and needs only
110/230 V power supply. The front panel controls ensures easy operation
and the benchtop system is ideal for laboratory work and experimental
research.
The AdjustiK™ system is also available in the 1µm range as the AdjustiK™
Y10 and with output power up to 10W as the BoostiK™ series (please see
separate datasheets).

Thermal Tuning
All Koheras fiber lasers are equipped with thermo electrical temperature
controllers (TECs). The TECs not only stabilizes the operation of the laser
desensitizing it to environmental temperature fluctuations, but also makes
it possible to achieve considerable tuning of the center wavelength by
changing the operating temperature of the laser. At standard room temperature (around 20-30°C or 68-86°F) the laser can be thermally tuned an
industry leading 1000 pm. Approximately 350 pm above normal operation
and 650 pm below. Please note, that if the laser is operated in very cold or
hot environments close to the temperature limits, this tuning range is truncated on either the upper or lower side.
