Typical linewidth can be narrowed down to Ultra-Narrow Linewidth < 5KHz when using Integrated InfraRed Light Module (I2LM) BF-series with high precision laser driver and temperature controller. Further precision wavelength (DOWN TO PICOMETER RANGE) CAN BE ACHIEVED THROUGH TUNING THE INTERNAL TEMPERATURE OR DRIVE CURRENT.
