6300 New Focus High-Power Velocity Tunable Diode Laser Controller

The Velocity Series is the most versatile line of external-cavity tunable diode lasers manufactured by New Focus. Designed for your most demanding applications, these lasers offer continuous tuning over wide wavelength ranges, fast linear sweeps, excellent tuning resolution, and narrow, stable linewidths.

The Velocity Series laser-cavity design and proprietary manufacturing procedure ensure fast mode-hop-free tuning over the entire wavelength range and superior wavelength repeatability and precision with a greater than 40-dB side-mode suppression ratio. The precision-engineered mechanical drive-train has a fine-frequency piezo control that allows you to set the laser's wavelength with a resolution of 0.02 pm. And unlike lasers driven by stepper motors, the Velocity's tuning is truly continuous and monotonic.

The New Focus 6300 series External-Cavity Tunable Diode Laser is a stable, narrow-linewidth source of tunable light. The 6300 series laser can be operated manually from the front panel of the controller or remotely using computer control.

The 6300 series laser incorporates a simple, stable mechanical design with a minimum number of optical components. Low-noise analog circuits precisely set critical operating parameters, such as diode temperature and current. Digital control facilitates remote operation and computer interfacing. The 6300 is a modular system. The same control unit will work with any 6300 series laser head. The control units work in both manual and remotely programmed modes and are compatible with RS-232 and GPIB addressing.

Microprocessor-based motion control allows you hands-free wavelength scanning capability. You set the start and stop wavelengths and scanning speed and the microprocessor-controlled DC motor takes care of the rest. The unique cavity design assures continuous tuning with minimal mode hopping.

Five LED digital readouts display important operating parameters including wavelength and diode temperature. Inputs are available for low-speed (1 MHz) and high-speed (up to 300 MHz) diode current modulation.
