TA-FHG pro
High-power, tunable, frequency-quadrupled diode laser
• Two resonant frequency doubling stages • Wavelengths: 190 .. 390 nm, up to 500 mW
• SUV-option - unprecedented DUV power & lifetime • Digital control with AutoAlign and PowerLock
The TA-FHG pro is a tunable, diode-based laser source in the deep UV spectral range. The system consists of an external cavity diode laser, a high power semiconductor amplifier (TA), and two cascaded second harmonic generation stages (SHG pro). Alternatively, it can be equipped with a fiber amplifier (FA) or Raman fiber amplifier (RFA). It provides tunable laser radiation for spectroscopy, laser cooling, holography and interferometry.
Applications
• Two photon spectroscopy (e.g. Hydrogen) • Atom optics: laser cooling & trapping (e.g. Hg, Mg)
• Ion laser cooling & trapping (In+, Mg+, …) • Metrology (atomic clocks)
• Optics tests in semicon inspection • Angular resolved photoemission spectroscopy (ARPES)
• Stimulated Raman scattering (SRS)
Options
• SUV-option - Unprecedented DUV power and lifetime
• AutoAlign: Fully-automated coupling into TA, SHG and FHG cavity
• 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: DLC ext + DigiLock 110, or DLC ext + PDD 110 + FALC 110
