Newport超低噪聲激光二極管驅(qū)動器，500 mA，電池供電

概覽

The LDX-3620B is a battery powered, ultra low noise current source, optimized for narrow linewidth or stable wavelength laser diode applications. The all new instrument provides a precision current output with <100 nA rms noise and <10ppm stability. The current source can be operated in one of two output ranges in constant current or constant power operating modes. Additionally, two AC or DC coupled modulation inputs, fine and coarse, can control the current source for precise laser diode wavelength or linewidth tuning with a bandwidth up to a 1 MHz.

All of ILX Lightwave’s proven laser diode protection features are designed into each model, which include adjustable current limits, a floating output, shoring relays, slow turn-on circuits, and transient protection during power up and laser operation. Error indicators help resolve set up problems quickly such as open circuit and power limits.

Additional features include long battery life between charges, a battery charge mode and front panel charge indicator making the LDX-3620B a reliable test instrument for low noise, precision laser wavelength control applications. The LDX-3620B is compatible with a large selection of ILX Lightwave laser diode TO-can, butterfly, and DIL laser mounting fixtures with interconnect cables for fast, easy system set up.
