A tunable laser (alternative spelling: tuneable laser) is a laser the emission wavelength of which can be tuned (i.e. adjusted) (→ wavelength tuning). That tuning is usually possible during operation, i.e., it does not only mean that a certain wavelength can be permanently set in …

Thorlabs' selection of tunable lasers includes benchtop sources with wide tuning ranges in the C-band (1528 nm - 1566 nm) or L-band (1570 nm - 1609 nm) and rack-mounted sources with tuning ranges in the O-band (1250 nm - 1350 nm) or C+L band (1520 nm - 1630 nm), and MEMS-VCSEL swept sources with 1060 nm or 1300 nm center wavelengths and a 100 ...

Efficient tuning of the emission wavelength of various wideband laser crystals like Ti:sapphire, Yb:YAG, Yb:KGW as well as dye lasers and optical parametric generators is achieved by means of wavelength tuning devices offered by ALPHALAS. These include reflection and transmission diffraction gratings, intracavity etalons, dispersive prisms and ...

Abstract: Tunable semiconductor lasers continue to be in just about everyone’s list of important components for future fiber optic networks. Various designs will be overviewed with particular emphasis on the widely tunable (>32nm) types. Why Tunable Lasers? Current market conditions.... Why Tunable Lasers? Cortek-Nortel-Bookham?

Many types of tunable lasers can produce tunable continuous-wave (CW), nanosecond, picosecond, or femtosecond output. Their output characteristics are governed by the laser medium used. A fundamental requirement of tunable lasers is their ability to emit over an extended wavelength range.

horlabs' tunable lasers are all based on external cavity tunable laser technology with tuning ranges up to 150nm. Since they are able to continuously tune or step between ITU grid wavelengths, Thorlabs' tunable lasers are ideal for both test and measurement as well as for research and development.

Benchtop External Cavity Tunable Laser. Our company manufactures and sells tunable lasers (the TSL series) which can achieve external longitudinal single-mode oscillation using a grating to select wavelength (Figure 1).

Feb 14, 2024 · Discover essential insights on tunable diode lasers, their applications, types, and selection advice for engineers and buyers.

5 days ago · Several tunable mode-locked Cr:ZnS/Se lasers have also been developed, but their spectral widths remain broader and their wavelength tuning ranges are restricted. 25,32,33 One notable example is a Cr:ZnSe laser mode-locked using a nonlinear mirror and employing a fan-out PPLN for spectral narrowing and wavelength tuning.

Santec has brought all its experience and knowledge gained over the past 35 years to its all-new 7th generation tunable laser. The TSL-775 is a very high specification tunable laser with flexibility in operation to ensure suitability for a wide range of applications.
