DL-SHG pro
Tunable, frequency-doubled diode laser with digital control DLC pro
• Resonant frequency doubling stage
• Wavelengths: 320 .. 680 nm, linewidth < 500 kHz
• AutoAlign, PowerLock and FiberMon options
• Digital remote control DLC pro
The grating stabilized diode laser SHG pro is a medium power solution, for applications such as spectroscopy of atoms, ions and molecules, laser cooling and interferometry. Designed in TOPTICA’s proprietary pro technology, it combines best performance and ease-of-use – at moderate initial and operating costs. The system now includes fully-automated push-button coupling optimization into the SHG cavity and the output fiber. The package comprises a solid laser head and a DLC pro control rack. It can be upgraded to a TA-SHG pro, if an appropriate amplifier source is available.
Applications
• Laser cooling of atoms (e.g. Na, Yb, Sr, Cr)
• Laser cooling of ions (e.g. Ba+, Li+, Ca+, Yb+)
• Optical pumping and Rydberg excitation
• High resolution spectroscopy of molecules, atoms or solid state systems
• Stimulated Raman scattering (SRS)
• Nitrogen vacancies
Options
• AutoAlign: Fully-automated coupling into SHG cavity and fiber (with FiberMon option)
• FiberMon: Measure and optimize the fiber-coupled laser power
• Double Piezo Lock: High-bandwidth stabilization of the SHG pro resonator (recommended)
• EOM/SHG pro: Electro-Optic Modulator for error signal generation (alternative to laser current modulation)
• FiberDock Probe: Fiber coupling of probe beam
• FiberDock SHG: Fiber coupling of SHG output beam
• Additional regulator modules for seed laser: DigiLock 110, FALC 110, PID 110
• Upgrade to TA-SHG pro
