A laser torch is a handheld device that uses a laser to cut a variety of materials.


The laser torch works by creating a laser, using a diode, powered by a rechargeable sarium krellide power cell. The laser travels through a coiled micrometric optical fiber containing trace amounts of neodymium, increasing the energy of the laser to its desired strength. The laser is then discharged in pulses through a zinc selenide lens. The frequency and length of the pulses can be adjusted to fit the target material.


As the cutting laser itself is not visible to the naked eye, the torch emits a secondary laser in the visible spectrum to act as a guide. A set of forcebeam emitters at the cutting tip assist in the removal of molten material. For additional precision, gyroscopic sensors in the housing automatically steady the beam, compensating for minor hand tremors during the cutting process.


Laser torches vary in construction. Some manufacturers use a cylindrical form, while others opt for an angled pistol-grip shape. In either case, the main housing is fairly compact, and can be held easily in one hand.

Controls for altering the laser's focal point, pulse rate, and power output are commonly found near the grip.


Compared to other torches, laser torches make very precise cuts. At femtosecond pulse lengths, they are able to make cuts that are accurate to within 25 microns. The pulsatile nature of the laser greatly reduces the risk of thermal deformation at the cut site. This makes them ideal for any cuts that are near heat-sensitive equipment. In addition to metals, laser torches are capable of cutting a wide variety of non-refractive materials, such as wood, ceramics and plastics. However, they are not capable of cutting through materials thicker than 10cm, even less for some metallic alloys.


Though experienced engineers may be able to use laser torches as welders, the Starfleet Regulatory Agency does not condone their use for this purpose.
