The output wavelength of a VCSEL is current and temperature dependent so using
a low noise current source and regulating the chip temperature is usually
necessary to allow locking to an atomic transition.
Most VCSELS for such applications include a peltier module within the housing.

It cannot be too much, given the fact that these are used in
green laser pointers.
Though, I have to say I am astonished
One might then ask what the availability and pricetag is for nonlinear
chrystal needed for frequency doubling.
If it is esoteric enough to get and priced similar, well then the gain
is lost.

We employ a recently developed laser system, based on a low-noise telecom laser
emitting around 1.56 μm, to evaluate
