IQ <strong>Laser</strong> Head—<br />
combined wavelength<br />
wavelength 2<br />
The IQ laser head is a separated geometry apart from <strong>the</strong> laser driver that provides exceptional beam<br />
pointing stability and maximum heat transfer from <strong>the</strong> laser diode to <strong>the</strong> IQ’s base.<br />
k Thermal stability: The IQ laser head features a custom-made <strong>the</strong>rmoelectric cooler. Unlike o<strong>the</strong>r lasers<br />
that pull heat from one side of <strong>the</strong> laser diode, <strong>the</strong> heat in <strong>the</strong> IQ is removed from <strong>the</strong> diode’s largest<br />
heat-bearing surface: <strong>the</strong> bottom.<br />
k Optical quality: We use high-quality glass lenses to achieve optical superiority. For added beam quality,<br />
users may choose to incorporate a laser diode with integrated microlens to provide a circular, diffraction-limited<br />
beam with low divergence. See page 30 <strong>for</strong> more in<strong>for</strong>mation on various methods of beam<br />
correction.<br />
The IQ head is well-suited <strong>for</strong> a variety of <strong>OEM</strong> applications, including instrumentation and spectroscopy.<br />
Also available is a complete IQ laser system that includes a power supply, precision temperature controller,<br />
and IQ head with integrated <strong>the</strong>rmoelectric cooler.<br />

Our dual beam combiner merges <strong>the</strong> output of two IQ laser heads into a unique, co-linear beam. Beam<br />
combining is achieved by employing a polarizing beamsplitter in a reversed configuration. Two beams enter<br />
<strong>the</strong> beamsplitter and emerge as a single beam with random polarization.<br />
Beam combining offers two main advantages.<br />
k Merging similar wavelengths will double <strong>the</strong> power available at that wavelength.<br />
k The process makes it possible to merge two different wavelengths. For example, certain applications require<br />
<strong>the</strong> alignment of infrared beams. Dual beam combining allows users to mix infrared and visible wavelengths<br />
<strong>for</strong> an easy means of alignment.<br />
Most standard diode wavelengths can be combined.<br />
The dual beam combiner is compatible with our IQ laser drive electronics.<br />
