• Laser diode technology

    The commercial and industrial use of laser diodes has dramatically increased recently.  The optical characteristics, small size, and ruggedness of laser diodes have allowed many new uses to be commercialized.   The output of laser diodes is very bright considering their small siz

     


  • What is laser beam divergence?

     Beam divergence specifies how much a beam spreads out over distance. All our beam divergence specifications are full angle values. The beam divergence of an electromagnetic beam is an angular measure of the increase in beam diameter or radius with distance from the optical aperture or

  • What is bore-sight accuracy and beam pointing stability

    Boresight accuracy known as pointing accuracy, it is a measure of the angular difference between the beam propagating axis (where the laser beam is pointing) and the mechanical axis (where the laser housing is pointing). Pointing stability is a measure of how much the beam alignment drifts

     


  • Can we operate the ttl series lasers in cw mode

    Yes.. You can operate the TTL series lasers in CW mode.  For CW operation, just connect the white wire to the red wire.

     


  • Cdrh classification and labeling requirements for commercial laser products

    Here is a table of the CDRH classification and labeling requirements for commercial laser products: Class Max Power (mW) Logotype Warning Label Text ----------------------------------------------------------------------------- I <,= 0.39 None Required

     


  • What is the effect of temperature on the wavelength of lasers?

    The wavelength of a laser diode module shifts about 2 nm with every 10 degree rise in temperature.

     


  • What determines the lifetime of a laser module?

    Typical lifetime of laser diode modules are 25,000 to 50,000 hours.  If the laser diode temperature continues to rise exceeding the maximum operating temperature, the diode can be catastrophically damaged or the long term performance may degrade significantly.  If the laser diode'

     


  • How do you rate output laser power?

    The output power is the maximum power value at the exit of the laser housing.  All our lasers have their power rated after passing through the optical assemblies.  The power is measured according to CDRH specifications.   Each laser is classified by measuring the amount of o

     


  • What determines the visibility of the laser light?

    The visibility of a laser light depends on several factors. The first factor that determines visibility is the output power of the laser. The higher the output power, the higher the visibility.  Wavelength also determines the visibility of the laser light. The human eye

     


  • How do i select a fan angle for laser lines?

     The fan angle of a laser line specifies the angular spread of the laser beam at a particular distance. The length of the line (L) produced at a certain projection distance (D) is given by the formula L=2Dtan(q/2);where q is the fan angle. We have line lasers available with fan an

     


  • World star technologies - light spectrum ranges

    The visible light spectrum ranges from short-wavelength violet to long-wavelength red. Photons of light from violet end of the spectrum have the highest energies and the highest frequencies, while red photons have lower energies and lower frequencies. Beyond the range of our vision are the longe
