Laser projectors are a relatively new type of projector available for trial presentation. As illustrated below, this type of projector uses a single laser in laser-phosphor technology or individual red green and blue lasers to produce full color projection. Either design allows laser projectors to generate a larger wavelength of light resulting in a color gamut that is much wider with richer colors than that of traditional projectors. These rich colors are produced at a high contrast without compromising brightness. Because the amount of light varies greatly from courtroom to courtroom, often with little to no control over the lighting, the colors, contrast, and brightness improvement of laser projectors make this type of projector highly favorable for courtroom use.
Additional advantages of laser projectors are that they power on and off almost instantly, have lower cooling needs which result in quieter operation, and the life span is much greater than other projector types. Laser projectors have approximately 10,000-20,000 hours of lifespan. In contrast, the average lifespan of regular projector lamp is about 2,000 hours. While the prices of laser projectors can be slightly more expensive, the vast differences in maintenance costs due to longevity, should prove laser projectors to be a cheaper alternative after the first 6,000-10,000 hours.
