These air-cooled ion laser systems are compact devices that produce high-quality, linearly polarized output that can be tuned over
a wide variety of wavelengths. The 35 LAP 321 and 35 MAP 321 are
extremely compact argon-ion lasers, less than 15 inches in length
(excluding cables). The somewhat longer 35 LAP 431 and
35 MAP 431 are argon-ion lasers that produce as much as 195 mW
multimode and up to 130 mW with a clean Gaussian TEM00 mode.
The model 35 KAP 431 is a mixed-gas (argon/krypton) laser with
nine selectable wavelengths ranging from 476 nm (violet) to 676 nm
(red). To select a wavelength, the operator simply turns a calibrated
micrometer on the back panel of the laser head. This rotates the
full-dispersing prism assembly and determines the output.
A switching-regulated power supply, equipped with both current and light-feedback regulation systems, is a standard feature.
Light regulation tightly controls the laser output to maintain constant power and low beam noise over long periods of time. The
power supply has outstanding power factor correction (greater than
90%), meets all relevant U.S. and European electrical emission standards, and proudly displays the CE mark. The systems are shipped
with integral forced-air cooling. For information on remote cooling,
please contact your nearest Melles Griot sales office.
