The DFB design can provide a very wide mode hopping single-frequency operating range (50 mA to 500 mA), while maintaining a Lorentz line width of 100 kHz and typical relative intensity noise (RIN) of -150 dBc/Hz. By adjusting the current or temperature of the laser chip, the wavelength can be tuned. The typical temperature tuning range can reach 1.6nm (with the chip temperature adjusted to 20 °C). When tuning the temperature, the DFB13TK operates at a single frequency without the need to adjust the current simultaneously.
This system is equipped with two analog current modulation ports (AC and DC coupling) and one analog temperature modulation port. The laser frequency can be locked to the optical cavity or reference cavity through the servo circuit, thereby building a stable laser system. Connect the laser to a PC and use the command-line interface to achieve remote control.
The optical output of this laser is a fiber-coupled output through the FC/APC socket (2.0mm narrow key). In order to achieve the best performance
