We were able to miniaturize a unique laser.  Eventually it will be widely applicable

The titanium and ruby ​​laser is a unique devicea tunable solid-state laser. It operates in the 690-1080 nm range and is used in optics, spectroscopy, and neuroscience. It can generate very short femtosecond pulses. However, these unique properties are associated with large dimensions of more than 2 cubic decimeters and a high price of hundreds of thousands of dollars. If that were not enough, it requires laser pumps to operate, each of which costs $30,000. Therefore, titanium-sapphire lasers are not as widely used as they deserve.

Stanford engineers have created a titanium-sapphire laser on a chip. The device is four times smaller (10,000x) and three times cheaper (1,000x) than previously produced lasers. This is a complete departure from the current model. Instead of using one large, expensive laser, laboratories will be able to have hundreds of these lasers on an integrated circuit. And all you need to pump it up is a simple laser pointersays Professor Jelena Vuković, lead author condition Description of mini laser.

Titanium and sapphire devices are valuable because of their wide operating range and their ability to generate very short pulses. Thanks to the work of Stanford University scientists, they will be able to spread widely.

The new laser operates in the 700 to 1000 nanometer range. It could be used in quantum physics to build quantum computers. In neuroscience, it will be used in optogenetics to control neurons using light. The miniature lasers could be placed in different types of probes and probes used in scientific experiments. It would be useful in ophthalmology, where it could be used during eye surgery and to image the condition of the retina.
