Toptica eagleyard’s RWL series of Fabry-Perot ridge waveguide laser (RWL) diodes operate on a single transverse resonator mode. This leads to high power output (100 up to 800 mW in cw mode) with diffraction limited beam profile. However, multiple axial (longitudinal) modes may occur which can lead to differing optical frequencies. The frequencies are separated by the free spectral range of the resonator given by the reflecting facets of the laser chip.
Additional features such as collimation optics for optimum beam quality or a thermoelectric cooling module for more stable frequency performance can be integrated in the package on request. Direct temperature control of the chip enables optimum wavelength stability and better heat dissipation under continuous high-power operation.
