Project Summary
  There are widespread commercial applications of lasers, such as laser cutters, laser pointers, and laser printers, just to name a few. Due to their well-defined frequency, narrow divergence, and high intensity, lasers are used in many different fields, including medicine and science. Currently, most lasers used are either inorganic or crystal lasers. However, those lasers are relatively inflexible compared to organic lasers, due to their fixed color, difficult manufacturing process, and high production costs. Therefore, many researchers have begun to investigate the more versatile organic laser. The goal of our work was to increase the versatility of the organic laser by making it transparent, durable, and cost-effective. In this study, we first recreated the organic laser of Kozlov et. al., 2000 to learn how to operate the machinery necessary to create organic lasers. Next, our study designed a setup to test organic lasers. Through educational guesses and trial and error, a system to effectively test the organic lasers was successfully created. Lastly, we created a more versatile laser using a glass substrate and the plastic lid of a takeout box from a local restaurant. The results showed that the laser we built successfully lased while being transparent. The plastic laser, judging by the substrate alone, was about 100,000 times cheaper than the substrate used by Kozlov et. al., 2000. This advancement in creating a cost-effective, durable, organic laser is an important step in revolutionizing its mass production and expanding its applications.

My name is Sung Wan Huh and I am a senior. This is my first year in Breck’s Advanced Science Research program
I'm from Korea and came to US in 5th grade. I've been an international student at Breck for 6 years.
I'm interested in Physics and Mathematics, and I play cello as a hobby. I've played since I was 4, and I play in Breck Chambers Orchestra and in Minnesota Youth Symphonies. 
In my free time, I like to sleep.
