RLD Series

Desktop Raman Pump Laser

IPG Photonics’ RLD Series fiber lasers are conveniently packaged for use in a laboratory environment. Everything is contained in one desktop instrument including a Raman laser with up to 30 W output power. The front panel includes a monitor display, on/off key switch, power control and fiber outputs. The RS-232 or GPIB port on the rear panel allow computer control of the module. Standard RLD fiber lasers provide an optical output in the range of 1100-1700 nm as specified by the customer. Typical laser output is provided by a 1.5 meter, standard SMF-28 optical fiber cable with I/O connectors. The front panel provides user control of the amplifier output power and readout of the pump diode current and temperature.
