1. What is semi conductor diode laser?
Semiconductor diode laser is a specially fabricated pn junction diode. It emits laser light when it is
forward biased.

2. What is LASER?
The term LASER stands for Light Amplification by Stimulated Emission of Radiation. It is a device
which produces a powerful, monochromatic collimated beam of light in which the waves are coherent.

What happens if DC supply is applied to the transformer?

If DC supply is given to the transformer, the current will not change due to constant supply.
So the mutual induction is not possible and thus the transformer will not work.
The primary winding resistance is very small.
For DC supply, the primary winding inductive reactance is zero.
So the primary will draw very high current for dc supply, consequently extra heat generated and thus the transformer get damaged.
Hence the DC supply should not be applied to the transformer.
What is ....etc
