CWA.L.NB – Narrow Bandwidth DFB Diode Lasers

Narrow Bandwidth CW laser diode modules using DFB diode technology

Redphoton® CWA.L.NB Series – 760 nm – 1060 nm

The DFB diode lasers of the CWA.L.NB Series are highly-stable, temperature-stabilized diode lasers with extremely narrow spectral bandwidth of typically <2 MHz and <0.005 picometer and coherence lengths of up to 250 meters. As a result of their intelligent laser controller with interface RS-232, these lasers can be integrated seamlessly into applications and controller. Through the standardized Command Line Interface (CLI), you have at all times full control of all parameters of the laser, such as e.g. laser diode temperature, laser powers and currents, operating modes and lots more. The high-precision temperature stabilization to a maximum diode temperature variation of <0.02°K, and the stable power source for the laser diode, enable extreme power stability and very low noise levels.
The systems consist of a laser head and a laser controller in the EMC-screened modular housing with supply voltage input 24 V DC, according to industrial standard. The integrated modulation inputs for analog power modulation with up to 1 kHz, and TTL modulation with up to 10 kHz, enable integration into control and measurement processes. As in case of all lasers of the Bluephoton® and Redphoton® series, the laser head can be very simply adapted to customer specifications by the use of the modular principle.
