These lasers are called grating-tuned external- cavity lasers. External-cavity lasers have been known as tunable sources for a long time and are often used in lab measurements, but have some disadvantages, such as poor power stability, tun ing linearity, and wavelength stability.

Tunable external-cavity diode lasers (→ tunable lasers) usually use a diffraction grating as the wavelength-selective element in the external resonator. They are also called grating-stabilized diode lasers.

The common Littrow configuration (see Figure 2a) contains a collimating lens and a diffraction grating as the end mirror. The first-order diffracted beam provides optical feedback to the.

Mroziewicz. The external cavity diode laser (ECDL) uses the LD chip as gain element and external reflectors as cavity mirrors, instead of the cleaved facets of LD chip. The cavity length can then be extended for a longer photon lifetime; and the external reflector may have strong wavelength selectivity to suppress mode competition by: 7.

An external cavity has been developed for use with commercial diode lasers. It uses a diffraction grating at grazing incidence for wavelength selection and output coupling.

We have observed tuning of the laser frequency over a THz (48 cm-1) range by rotation of the external grating. This result was obtained without anti-reflection coating of the laser output by: 4.

The first report of a grating-tuned ring ECL operating in strong-feedback mode was by Bogatov and coworkers [86]. The active element was an AlGaAs heterojunction optical gain medium with a. Two external cavity diode lasers (ECDL) in the Littrow configuration are used as the infrared laser sources.

The ECDL can be electronically tuned from to nm. The line-width of each laser is ~2 MHz with an output power of ~ mW. The lasers are very sensitive to feedback. We investigate theoretically the tuning characteristics of a diode with an external grating cavity for which one of the external-cavity modes and the peak of the grating reflection scan synchronously.

We show that the tuning curve is hysteretic. Moreover, the theoretical analysis reveals that frequencies at turning points of the hysteretic tuning curve are related to the external cavity mode.

Within the last few years, divalent-transition-metal-doped II-VI material class has been proposed as source of new tunable mid-IR lasers. Cr{sup 2+} is a prime laser candidate on account of its high luminescence quantum yield and the expectation that ESA would be absent.
