DenseLight BF10

The DenseLight BF10 is a series of ultra narrow linewidth laser designed for applications in optical metrology & instrumentation and optical gas & chemical sensing, requiring narrow spectral linewidth, excellent SMSR, power stability, and a very highly wavelength stable laser output. BF10 is complete with a DenseLight 14-pin BTF package laser, integrated laser driver and temperature controller. It is available over a wide wavelength range across the O, E, S, C and L bands, and can be customized with various options to meet your specific needs. The DL-BF10 series comes with 2 direct modulation inputs (analog input: BW 20MHz & digital input: BW200MHz).
