Users requiring the maximum possible mode-hop-free tuning and/or current range should select the current-tuning configuration, while users wishing to thermally tune the output wavelength without impacting the output power should select the temperature-tuning configuration. The Rep Rate selector on the back panel enables the user to either choose among three options for internally triggering the pulses, or to configure the laser to accept a user-supplied external signal to trigger pulse generation. Optomechanics, optics, opto-electronics, laser … As the system experiences effects of hysteresis, the width of these ranges will also change depending on whether the drive current is being increased or decreased. Because the laser's configuration provides excellent low-noise performance, it is likely the laser will not be the limiting factor at low-noise levels. The fiber's slow axis is aligned parallel to the connector key. However, the single-electrode DBR will have periodic mode hops in its tuning curve. Thorlabs specializes in the building blocks for laser and fiber optic systems. A wide variety of applications require tunable single-frequency operation of a laser system.
