Lambdameter LM-007 Precise and Repeatable!

 

"We are quite impressed with the ease of use of your lambdameters."
-Yale University

 

Lambdameter LM-007 is a device for precise measurement of absolute value of Laser wavelength. Its main applications are: High resolution spectroscopy, Laser wavelength control during isotope separation, alignment, stabilization, tuning, and testing of narrow-band laser systems, including injection-seeded solid-state lasers.

The Lambdameter can also be used as a Laser Spectrum Analyzer. LM-007 has no moving parts, its operation is based on simultaneous detection of interferometer patterns of four Fizeau interferometers manufactured as a single fused silica block and can be used for both CW and pulsed laser radiation.

 

Operation of LM-007 requires a 100% IBM PC compatible machine that can be supplied either by the user or by the manufacturer.

Lambdameter LRL-005 Sensitive and Affordable!

 

Lambdameter LRL-005 is a low-cost device for measurements of absolute value of Laser wavelength. Its main applications are Laser wavelength control, Laser spectroscopy, Laser isotope separation, alignment, tuning, and testing of tunable laser systems. The device will be extremely useful for the users of diode lasers, tunable dye and solid state lasers or OPO's. For broadband sources, like multi-mode diode lasers, LRL-005 may be used as a spectrum analyzer.

Operation of the device is based on multichannel detection of a diffraction pattern, produced by a concave diffraction grating.

Operation of LRL-005 requires a 100% IBM PC compatible machine that can be supplied either by the user or by the manufacturer.

Sensitivity: LRL-005

The sensitivity of LRL-005 is very high, but exact numbers depend on many factors. Among them are: wavelength, source spectrum span and shape, transverse mode structure, quality of coupling of the beam with a fiber coupler (divergence), wavelength-dependent losses in the fiber, detector exposure time and so on. Some reference numbers, giving the estimates of device sensitivity are listed in the following table. Perfect coupling of the laser beam with a fiber coupler is assumed.
