I've worked with neutral atom QCs before (though am not a laser tech): keeping lasers locked is a massive pain in the ass.

> more so effort should be spent on making the technology cheaper and more accessible

Lasers are weird because the techniques to generate light at different frequencies differs a lot. "Telecom wavelengths" used in, say fiber optic networking, is super cheap and widely available, but these QCs often need different wavelengths that aren't mass produced. Some systems even need the ability to tune the wavelength precisely and the range of that tuning is another spec that can matter. I'm sure these QC companies would love for this to be more stable and cheaper, but the reality is without demand (of which there is little), it's just not going to happen.
