Request a quoteThe PureSpectrum™ LM is a no-fuss laser module that combines a DFB semiconductor laser diode, a low-noise current-source, and temperature-controller, all into a single package. The compact size of the LM does not sacrifice power—the output from an LM can be as high as 100 mW. The LM operates single-mode with a linewidth less than 1 MHz and tunable over a 50 GHz range with 5 MHz resolution. The compact, high-power and reliable LM laser comes ready-made for integration in embedded designs and OEM applications.
TeraXion developed the PureSpectrum™ LM to be a reliable and easy-to-integrate seed laser source for OEM applications, such as lidar and metrology. The semiconductor-based, fully-integrated unit eliminates complicated alignment and integration time, and the high output-power allows for a better signal-to-noise ratio.
- The all-in-one construction of the PureSpectrum™ LM combines a high-power diode with ultra-low noise laser drive electronics, making it a natural choice for OEM applications where easy integration is paramount.
- The high output power of the PureSpectrum™ LM exceeds any other laser of its size and construction.
