A certain type of Laplace transforms, which is called
L
2
-transform, was
introduced by Yürekli and Sadek [4]. Then these transforms were studied in
more details by Yürekli [5], [6]. Purohit and Kalla applied the
q
-Laplace
transforms to a product of basic analogues of the Bessel function [7].
On the same manner, integral transforms have different
q
-analogues in the
theory of
q
-calculus. The
q
-analogue of the Laplace type integral of the first kind
is defined by [8] as

In this paper we build upon analysis of [8]. Following [9], we discuss the
q
-Laplace type integral transforms (4) and (7) on the
q
-Bessel functions
,
and
, respectively. In Section 2, we recall some
notions and definitions from the
q
-calculus. In Section 3, we give the main
results to evaluate the
q
-analogue of Laplace transformation of
q
2
-Basel function.
In Section 4, we discuss some special cases.
2. Definitions and Preliminaries
In this section, we recall some usual notions and notations used in the
q
-theory.
It is assumed in this paper wherever it appears that

number
a

q
