  This article provides an introduction to one of the most efficient laser
stabilization techniques - the Pound-Drever-Hall (PDH) method. The aim of the
experiment is to build the PDH stabilization apparatus from scratch. I describe
all the necessary theoretical treatment to formulate the technique and then
describe it as I have experimentally implemented in the lab. All major sources
of noise are discussed and noise tackling methods are implemented. All the
equipments used are also described in detail for their principle and working.
