Advantages and disadvantages of LASER diode

The terms stand for LASER full form Light Amplification by Stimulated Emission of Radiation. It can produce coherent radiation in the visible or in an infrared spectrum when current passes through it. It can be used in optical fiber systems, compact disk players and also some remote control devices. Here this post gives information about the advantages and disadvantages of LASER diode to know more about it.

Advantages of LASER diode :

  • Simple economic design
  • It has low power as compared to other types of laser diodes
  • Better modulation capability
  • The laser diode has a high coupling efficiency
  • It can be used at high temperatures
  • It gives high optical power
  • In this diode cheaper device to produce laser output  
  • It has a smaller size as compared to other types of laser diodes
  • Production of light can be precisely controlled
  • Laser diode to transmit optical output powers between the range of about 5 and 10 mW
  • Low spectral width (3.5 nm)
  • Compact
  • It is easily manufactured in arrays
  • The delivered system not as expensive as hard tissue laser diode
  • Ability to maintain the intrinsic layer characteristics over long time periods

Disadvantages of  LASER diode :

  • It produces a more divergent laser beam
  • They require big and costly optics for a large source of size
  • It has a critical heating problem
  • Hight drive current to drive the large laser for pellets
  • Expensive
  • A speckle pattern appears as two coherent types of light beams to added or subtracts their electric field depending upon their relative phases at the end of the fiber optic device
  • Poorly absorb in hard tissue and hydroxyapatite
  • Current produces unfavorable thermal characteristics 
  • Necessitates the use of cooling and power stabilization
