Advantages & disadvantages of Laser diodes

The advantage of Laser diodes are given below:

• The Laser diode operates in lower power as compared to other laser.
• It gives high power output as compared to other lasers.
• Laser diode is smaller in size as compared to other types of laser.
• It is easily manufactured in arrays.
• It is the cheaper device to produce laser output.
• Laser diode has high efficiency.

Some of the disadvantage of Laser diodes is given below:

• Laser diode produce more divergent laser beam.
• They are requires big and costly optics for large source size.
• It has critical heating problem.
• They are requires high drive current to drive the large laser pellets.
