The committee appreciates your thorough review of the proposal and support provided to the student.
Complete the following sections and
1, Project Oescription and Significance
answer ALL questions.
What is your research question/creative activity goal?
The goal of this research project is to develop a red-green-blue (RGB) laser with application to sensing,
spectroscopy, and data transfer. Most lasers are designed to have one color output. I will build a laser that will have
three different outputs (red, green, and blue) which, when combined, outputs a single laser beam that is white in color.
How does your research question/creative activity flt with research done in your discipline?
(i.e. research, methodology, nature, research approach, fieldwork)
This research project will be designed using electronic components, including a power supply and laser
diodes, and electrical and mechanical engineering CAD software (Pspice & Solidworks) to model the electrical and
mechanical systems in this laser prior to the build. The design also incorporates optics components such as lasers
and dichroic beam combiners to merge the laser beams and produce the RGB iaser output.
How is this project paft of your coursework or degree requirements? (be as speclflc as possible)
This project is undertaken as part of the Physics 333 Optics course which fulfills an electave for the electrical
engineering undergraduate curriculum at St. Cloud State University. The focus of this pro.ject is the design and
construction of an optical system related to multiple disciplines including Physics, Electrical Engineering, and
Mechanical Engineering.
2. Project Objectives
ldentify the objectives clearly and explain how they enable you to answer your question or reach your goal.
1. Design and analyze a Pspice model of the power supply to utilize the laser diodes and electronics in this
system efficiently. This will result in knowing the amount of current and voltage needed in the entire system as well as
where it should be distributed within the system.
2. Design a Solidworks model of the laser combiner system. This step will result in knowing where the dichroic
beam combiners should be located as well as where the laser diodes and their switches should be located. All
theoretical calculations should be completed previous to this step.
3. 3D print the exterior shell of the laser combiner using the previous step.
4. Build the large scale lab model of the laser combiner. This will include all beam combiners and laser diodes
as well as the working power supply. The laser combiner casing will not be included in this model. This step is to
assure beam combiner placements are calculated correctly and laser diode placements are correct. This step is also a
test stage to assure all systems are working together correctly and the laser is giving all correct outputs. Laser outputs
will be measured with an Ocean Optics USB4000 spectrometer to assure all outputs are correct from the laser.

5. Assemble and test the fully functioning RGB laser system. This step involves taking all components from the
large scale lab model and compacting the assembly to fit within the 3D printed shell. This step must be completed
carefully as it is crucial everything be placed correctly as it was in the large scale model to ensure functionality.
3. Methods and Analysis
What methodology willyou use?
This project will follow the methods used in the engineering design process which relates to the scientific
method.
Step 1 is to define the problem clearly
Step 2 is to complete the necessary research prior to building and modeling
Step 3 is to specify known requirements in the system (such as currents, etc in system design)
Step 4 is to find possible solutions to step '1
Step 5 is to choose a solution that best answers any design requirements
Step 6 is to begin developing the product
Step 7 is to build a prototype (in this case a large scale model)
Step 8 Test prototype for any existing problems
Step 9 Build final product
How will you collect your data or pertorm your creative activity?
Data from the output of the laser will be collected using the Ocean Optics visible spectrometer to measure
wavelength of the laser at the different output stages of the laser. A multimeter and an oscilloscope will be used to
measure voltage and current in the laser system. An optical photodiode power detector will measure laser intensity.
How will you analyze your data or assess your activity?
Success will be determined using a visible spectrometer and a computer. A visible spectrometer measures the
wavelengths of the laser output, and can resolve different colors in the white light beam. Three colors will be present
in the spectrum simultaneously if it is working correctly.
4. Project Plan
Explain your timeline and demonstrate that you can complete the project within your timeframe.
Phase '1: Design PSpice model of variable power supply
Phase 2: Research lasers and uses
Phase 3: Purchase equipment and begin large scale model of laser combiner
Phase 4: Test system and design laser casing
Phase 5: Compact design to fit casing and finish laser build
Phase 6: Retest to assure functionality
5. ltemized Budget
Provide itemized budget with explanations and demonstrate you will have adequate resources to conduct the work
properly. An itemized budget MUST be provided to qualify for this funding.
