If any of the light passes eg aur whole room light or light rays from outside then also it will make a noise in buzzer

[@asadalam]

Yess...the LDR must be covered with some covering to prevent light from falling on it....at the same time ensure that laser is falling continuously on the LDR

Mera wala jab me mera haat deta hu tab nahi bajta he par jab me haat laser se bahar lata hu to bajta rah ta he

It means you are using NPN transistor... please use PNP transistor....i.e. use BC557 only.
