Experiment: Q-switching for Nd:YAG laser – 8000697

Objective: Q-switching circuit for Nd:YAG laser with Cr:YAG module Q-switching of a laser makes it possible to generate short, high-energy pulses. It works by controlling the laser threshold by increasing or decreasing resonator losses. You are to implement a passive Q-switching circuit with the help of a Cr:YAG module and then record the laser pulsing […]

Experiment: Nd:YAG -laser, Frekvensfördubbling – 8000698

Objective: Frequency doubling inside the resonator of a Nd:YAG laser Materials often change their optical properties in strong electromagnetic fields. For instance, it is possible for the frequency of high-intensity laser light passing through such materials to be doubled. In this experiment, a KTP (potassium titanyl phosphate) crystal is used to generate green light with […]

Experiment: Nd:YAG laser – 8000696

Objective: Set up and optimise an Nd:YAG laser In this experiment an Nd:YAG laser with a diode laser pump is to be set up and optimised. Once the diode laser is calibrated for stable optical pumping and the resonator has been optimised, the system can then be used as an Nd:YAG laser. An investigation is […]

Experiment: Pockels Effekt (115 V, 50/60 Hz) – 8000770

Objective: Demonstration of Pockels effect in a conoscopic beam path The Pockels effect is an electro-optical effect in which an electric field within a suitable material splits a light beam into two beams polarised perpendicular to one another. This ability to produce optical birefringence derives from the differing refractive indices depending on the direction of […]

Experiment: Faraday effekt (230 V, 50/60 Hz) – 8000689

Objective: Demonstrate the Faraday effect and determine the Verdet constant for flint glass Optically isotropic, transparent, non-magnetic materials become optically active in a magnetic field. They rotate the plane of polarisation of linearly polarised light passing through them in the direction of the magnetic field because clockwise and anti-clockwise circularly polarised components of the light […]

Experiment: Michelson-Interferometer – 8000684

Objective: Demonstrate and investigate how a Michelson interferometer works In a Michelson interferometer a coherent light beam is separated into two rays travelling in different directions by inserting a half-silvered mirror in the path. The separated beams are reflected back along themselves and then recombined. The viewing screen then exhibits an interference pattern that changes […]

Experiment: Mach-Zehnder interferometer – 8000685

Objective: Demonstration of “quantum erasure” in an experiment by analogy Light itself can be described in quantum mechanics by means of wave equations. From this it is possible to derive the spatial distribution of the probability density in the form of the square of the modulus of the wave function. Light is therefore suitable for […]

Experiment: Michelsons Interferometer II – 8000787

Objective: Determine the refractive index of glass A Michelson interferometer can be used for interferometric measurement of refractive indices in particular because it is sensitive to changes in the optical path of a split beam of light. If the geometric path is kept constant, then refractive indices or changes in refractive index can be determined […]

Experiment: Prismaspektrometer (230 V, 50/60 Hz). – 8000772

Objective: Set up and calibrate a prism spectrometer A prism spectrometer utilises the dispersion of light into its spectral components by means of a prism to measure optical spectra. In order to measure wavelengths, it is necessary to calibrate the system since the angular dispersion is nonlinear. In this experiment the known spectrum of a […]

Experiment: Transmissionsspektra – 8000679

Objective: Record and interpret transmission spectra of transparent bodies A digital spectrophotometer is used to measure transmission spectra. In this instrument the transmitted light collected by an optical fibre is separated into its spectral components by a reflection grating using the Czerny-Turner principle and is projected as an image onto a CCD detector via two […]

Experiment: Bestämning av ljusets hastighet (230 V, 50/60 Hz) – 8000695

Objective: Determine the velocity of light from the transit time of short light pulses The fact that light is propagated at a finite speed can be demonstrated by a simple transit time measurement. This is achieved by using very short light pulses of only a few nanoseconds duration and determining the time for them to […]

Experiment: Fresnel Biprisma – 8000681

Objective: Generating interference between two beams using a Fresnel biprism. Refraction of a divergent light beam by means of a biprism separates the beam into two parts which, since they are coherent, will interfere with one another. The wavelength of the light used in the experiment can be determined using the separation of the virtual […]

Experiment: Malus Lag (230 V, 50/60 Hz) – 8000687

Objective: Verify Malus’ law for linearly polarised light. Malus’ law describes how intensity I of polarised light with an initial intensity I0, having passed through an analyser filter, depends on the angle of rotation of the filter. The intensity of the light is measured using a light sensor. Coach 7 license required!

Objective: Verify the inverse square law for the intensity of radiation from a source of light According to the inverse square law, the intensity of radiation from a light source, i.e. the power per unit area, is inversely proportional to the square of the distance from the source. This will be investigated in an experiment […]

Objective: Investigate the rotation of the plane of polarisation by sugar solutions Sugar solutions are optically active, in other words they rotate the plane of polarisation of any linearly polarised light that is passed through them. The direction of rotation depends on the molecular properties of the sugar. Thus, solutions of glucose and saccharose (sucrose) […]
