Fast tuning of external-cavity diode lasers.

چکیده
We report on a method for characterizing the tuning capabilities of small-bandwidth external-cavity diode lasers. The step response of a piezo-driven Littman-Metcalf external-cavity diode laser and the compensation of its optoelectromechanical frequency response is investigated. When an approximately 50-V compensated Gaussian pulse is applied to the piezo element, a detuning of 13.6 GHz is observed. This modification of the laser is useful for several spectroscopical applications and as a tunable seed laser for lidar applications.

Mode stability of external cavity diode lasers.
Mode stability is an important performance characteristic of external cavity diode lasers (ECDLs). It has been well established that the continuous mode-hop-free tuning range of a grating-feedback ECDL can be optimized by rotating the grating about a specific pivot location. We show that similar results can be obtained for other more convenient pivot locations by choosing instead the cavity len...
متن کاملTuning extension of a Difference-Frequency generation up to 100 nm using V-shaped external-cavity for the pump laser
In this research, tunability of a commercial diode laser has extended to about more than ± 11 nm using a V-shaped external-cavity fabricated around the laser. Although under normal condition it can be tuned up to about ± 4 nm just by changing its temperature and injection current. Such modified diode laser has then used in a difference-frequency generation (DFG) experimental setup as pump sourc...
متن کاملBroadly tunable high-power InAs/GaAs quantum-dot external cavity diode lasers.
A record broadly tunable high-power external cavity InAs/GaAs quantum-dot diode laser with a tuning range of 202 nm (1122 nm-1324 nm) is demonstrated. A maximum output power of 480 mW and a side-mode suppression ratio greater than 45 dB are achieved in the central part of the tuning range. We exploit a number of strategies for enhancing the tuning range of external cavity quantum-dot lasers. Di...
متن کاملTuning range and output power optimization of an external-cavity GaN diode laser at 455 nm.
In this paper we discuss how different feedback gratings affect the tuning range and the output power of external feedback diode laser systems. A tunable high-power narrow-spectrum external-cavity diode laser system around 455 nm is investigated. The laser system is based on a high-power GaN diode laser in a Littrow external-cavity. Both a holographic diffraction grating and a ruled diffraction...
متن کاملElectronically tunable single-mode external-cavity diode laser.
A six-stage birefringent filter placed in an external cavity of an AlGaAs diode laser is used to scan the laser electronically over 10.3 nm, hopping single modes of the external cavity. Continuous electronic tuning of the single mode over the free spectral range of the external cavity, 182 MHz, is also demonstrated by using a variable-phase plate. All tuning mechanisms use nematic liquid-crysta...
