All springs – including flexures – have been removed to create a robust, stable, and vibrationally inert device. Grating rotation and vertical alignment are uncoupled, allowing simple tuning over the full diode wavelength range without realignment. When used with a MOGLabs Diode Laser Controller, mode-hop-free scanning range of up to 40GHz and linewidth below 100 kHz can be achieved, with a broad range of AR coated and less expensive uncoated diodes. Diode replacement and re-alignment are easily accomplished by the end-user. Wavelength options extend from 368nm to 1620nm, and powers up to 250mW extra-cavity. Features Vibrationally inert Passive stability Wide tuning range Wavelengths from 368 to 1620nm Decoupled grating rotation and tilt Wide mode-hop free scan range Narrow linewidth Fast piezo feedback Precision alignment controls High bandwidth low latency modulation Diode protection circuit and relay Low frequency noise Applications Laser cooling and trapping Bose-Einstein condensation Quantum optics: squeezed light Electromagnetic transparency and slow light Time and frequency standards Laser spectroscopy Physics teaching labs Specifications LDL Wavelength/frequency 368nm to 1612nm Up to 250mW output power,diode dependent Linewidth Typically <200kHz,diode dependent Modulation 20MHz bandwidth,AC or DC coupled,20ns latency RF bias tee option:>2.5GHz bandwidth Coarse tuning range Up to 50nm for single diode Optical Beam diameter(1/e2) Typically 1mm x 2mm to 1.5mm x 4mm;diode-dependent Polarisation Linear 100:1 typical Thermal TEC ±14.5V 3.3A Q=23W standard Sensor NTC 10kΩ standard;AD590,592 optional Stability at base ±1mK (controller dependent) Cooling Water cooling connections optional(usually not required) Sweep/scan Scan range Up to 50 GHz;with MOGLabs controller,rate 4Hz to 70Hz Mode-hop free scan 10 GHz to 40GHz,diode dependent,with current feed-forward Piezo 0–120V or 0–150V,2 to 5μm Cavity length 1–3cm (5–15GHz FSR) approx.
