Visotek DL Diode Laser Series

The Visotek DL Series Diode Laser is a cost-effective, turnkey platform for operating a variety of diodes. The 19” housing includes a fiber coupled diode and power supply/driver electronics. Its microprocessor-controlled cooling system adapts the temperature of the diode to the output power, thus stabilizing the wavelength. Visotek can provide an off-the shelf solution or build a custom system that meets your needs, using diodes with output powers up to 250W. Air cooling is available for modules with output powers up to 50W. Systems with higher output powers are tap water-cooled. The DL series is a versatile low cost alternative to “doing it yourself.”
