The value is $N = 2.69 *10^{26} \ photons$

Explanation:

From the question we are told that

The power is $P = 510 \ W$

The wavelength is $\lambda = 10.5 \ cm = 0.105 \ m$

Gnerally the number of photon produced is mathematically represented as

$N = \frac{P * \lambda }{ h * c }$

Here is the Planck's constant with a value $h = 6.62607015 * 10^{-34} J \cdot s$

c is the speed of light with value $c = 3.0*10^{8 } \ m/s$

$N = \frac{ 510 * 0.105 }{ 6.62607015 * 10^{-34} * 3.0 *10^{8} }$

=> $N = 2.69 *10^{26} \ photons$
