Ruby Laser: A Powerful Source of Light and Energy

How does a Ruby laser produce radiation?

A Ruby laser produces radiation of wavelength 633 nm in pulses whose duration is 1.00 x 10^-29 s. If the laser produces 0.376 J of energy per pulse, how many photons are produced in each pulse?

(a) How does the laser generate such intense light and energy?

(b) What is the power delivered by the Ruby laser per pulse?

Answer:

(a) The Ruby laser harnesses the properties of a synthetic ruby crystal to produce intense pulses of laser light. By pumping the crystal with energy, it emits high-energy photons at a precise wavelength of 633 nm, creating a powerful beam of light.

(b) The number of photons produced in each pulse is 1.2 x 10^18, while the power delivered by the Ruby laser per pulse is 3.76 x 10^8 watts.

The Ruby laser is a remarkable tool that utilizes the properties of ruby crystals to generate powerful pulses of laser light. By exciting the atoms within the crystal, it produces photons with an energy wavelength of 633 nm, resulting in a focused beam of intense light.

The energy produced by the Ruby laser in each pulse is 0.376 J, which can be broken down into individual photons. By calculating the energy of each photon using the formula e=hc/wavelength, we can determine the number of photons produced in each pulse. In this case, the laser generates an impressive 1.2 x 10^18 photons with each pulse, contributing to its exceptional output of light and energy.

Furthermore, the power delivered by the Ruby laser per pulse is 3.76 x 10^8 watts, showcasing the immense power and efficiency of this laser system. The precision and intensity of the laser beam make it a valuable tool in various scientific and industrial applications, highlighting its significance in the field of photonics and laser technology.
