Frequency locking of tunable diode lasers to a stabilized ring-cavity resonator
نویسندگان
چکیده
We demonstrate a technique for locking the frequency of a tunable diode laser to a ring-cavity resonator. The resonator is stabilized to a diode laser which is in turn locked to an atomic transition, thus giving it absolute frequency calibration. The ring-cavity design has the principal advantage that there is no feedback destabilization of the laser. The cavity has a free-spectral range of 1.3 GHz and Q of about 35, which gives robust locking of the laser. The locked laser is able to track large scans of the cavity. Typeset using REVTEX

Frequency locking of tunable diode lasers to a rubidium-stabilized ring-cavity resonator.
We demonstrate a technique for locking the frequency of a tunable diode laser to a ring-cavity resonator. The resonator is stabilized to a diode laser that is in turn locked to an atomic transition in rubidium, thus giving it absolute frequency calibration. The principal advantage of the ring-cavity design is that there is no feedback destabilization of the laser. The cavity has a free-spectral...
متن کاملEfficient second-harmonic generation using a semiconductor tapered amplifier in a coupled ring-resonator geometry.
A new approach for efficient second-harmonic generation using diode lasers is presented. The experimental setup is based on a tapered amplifier operated in a ring resonator that is coupled to a miniaturized enhancement ring resonator containing a periodically poled lithium niobate crystal. Frequency locking of the diode laser emission to the resonance frequency of the enhancement cavity is real...
متن کاملSecond-harmonic generation and optical stabilization of a diode laser in an external ring resonator.
The second harmonic of the 842-nm output of a GaAlAs diode laser is generated in a KNbO(3) crystal in a resonant, external ring cavity. The diode laser is optically stabilized to the ring cavity through feedback from the counterpropagating fundamental wave, which is weakly excited in the resonator. We have produced 6.7 mW of tunable, narrowband radiation at 421 nm and have used that light to pe...
متن کاملDiode-pumped, single-frequency Cr:LiSrAlF6 ring laser.
The Ti:sapphire laser has become an established source for cw, watt-level, single-frequency power from 680 to 1050 nm, but the commonly used Ar-ion laser pump source is a disadvantage for many applications. Tunable, external-cavity, single-frequency diode lasers are available for portions of this wavelength region, but a given diode laser can cover a range of only 15– 25 nm. Cr:LiSrAlF6 (Cr:LiS...
متن کاملFrequency tracking and stabilization of a tunable dual-wavelength external-cavity diode laser
We show a unique dual-wavelength external-cavity laser diode with frequency tracking capability and obtain a stable beat frequency between the dual-wavelength output. By using a Fabry–Perot interferometer as the frequency discriminator and the time-gating technique in a servo loop, the peak-to-peak frequency fluctuations were stabilized, with respect to the Fabry–Perot cavity, to 86 kHz in the ...
