By means of the structure of an external cavity, the laser diode is forced to emit on only one single wavelength and to retain this. Since the spectral bandwidth is very large, particularly in case of laser diodes in the blue wave band, this can be very disturbing in some applications. The lasers of the CWA.L.WS/US Series solve this problem and enable employment of diode lasers in applications which require narrow-band emission and stable wavelength (for example, with employment of AO deflectors, AO modulators and other wavelength-sensitive optical elements). As a result of their intelligent laser controller with interface RS-232, these lasers can be integrated seamlessly into applications and controlled. 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 standards.
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.
