- These latest generation 14-pin butterfly packaged laser diodes from 3SP Technologies are fiber Bragg grating stabilized and offer up to 500 mW of output power.
- They are offered with a HI1060 fiber. These high reliability 976nm laser diodes are used as the first stage seed source for amplification / fiber laser applications.
- They have an integrated TEC with 10K NTC thermistor and a monitor PD. The wavelength is "locked" utilizing a fiber Bragg grating (FBG) located in a polarization maintaining fiber (PMF).
- The stabilized wavelength ensures that the laser emits light at a specific, known wavelength. This accuracy is crucial in applications like spectroscopy, sensing, and metrology, where precise measurements and reproducible results are essential. and wavelength stability prevents interference and simplifies the process of calibration and alignment.
