D2Series_Product

From Box to Locked in Under an Hour!

The D2-Series laser system is a complete turn-key solution that will be the easiest part of your experiments. Monolithic laser designs provide robust performance with piezo-less, non-mechanical tuning. Our Libbrecht-Hall current source and laser servo enable easy locking to atomic hyperfine transitions and cavities.

Non-mechanical, monolithic laser designs.

Supports both peak and side locking.

Servo signals accessible via front panel BNCs.

Unlock-jump-relock with external computer control.

With the grating located directly on the semiconductor chip, the DBR laser module provides the most robust performance and longest mode-hop-free tuning range. Include laser diode, collimation and circularization optics, optical isolator, and two stages of temperature control.

Contains a saturated-absorption spectrometer and a 12 MHz, shot-noise-limited photo-detection circuit. Temperature control of the rubidium cell and laser power normalization minimizes lock point drift.

Based on an ultra-low-noise design (Libbrecht and Hall, ‘93) with <100 nA rms current noise (below 1 MHz), 1 microA/°C temperature stability, and > 10 MHz current modulation servo input. Contains two temperature controllers to give 1 mK temperature stability.

A fast transfer function tailored to the diode injection current ensures the tightest lock. Double integrators give high DC gain and stability. Can be set to side lock mode or peak lock mode. 4 MHz FM sideband modulation in peak lock mode preserves system bandwidth and enables the laser servo to be used for Pound-Drever-Hall locking to optical cavities.

An external, low-noise linear power supply keeps 60 Hz and harmonics off your signals. This power supply may be used to drive up to four electronics modules.

D2-Series laser system comprising: i) electronics modules (background, left to right) laser servo, power supply, and laser controller, and ii) optical modules (foreground, left to right) DBR module and spectroscopy module.

Large mode-hop-free tuning by injection current or temperature.

Chip-sized external cavity design provides DBR-like performance with a narrower linewidth at more wavelengths. Includes chip-external-cavity-laser (CECL), collimation and circularization optics, and two stages of temperature control.
