I believe, from a technology standpoint, it's a power issue. But this series being Horatio Hornblower in Space originally, David probably decided he didn't want them in the storyline. But I've never officially seen why mentioned. ****** RFC said "refitting a Beowulfan SD to Manticoran standards would be just as difficult as refitting a standard SLN SD to those standards. In other words, it would be cheaper and faster to build new ships."

In the honorverse, lasers means X-ray lasers. They have issues with penetrating atmosphere. Not to mention shooting a concentrated beam of ionizing radiation around has certain issues with bystanders.

As to relative effectiveness of pulsars versus lasers, a single hand held pulsar dart has the muzzle energy of a 50 cal, and can be fired in a stream of 50 shots without recoil problems. A hand held laser would have to be pretty special to be more effective than a full auto Barrett with a 50 round magazine. RFC's universe, his rules. There have been discussions on many such topics, like computers 2k years hence not being much better than ours, wedges violating the 2nd law of thermodynamics, minimal tau at relativistic velocities, and fusion bottle energy densities. I just enjoy the story and his universe.

What I think is that compared to pulsar weapons they need a lot of energy to fire. For the amount of energy need to fire a hand held laser you can fire several pulsar bolts. Pulsar bolt also come in a variety of types for various uses.

Even with ultra dense power sources to reduce the size of the power source, a laser takes a fair amount of energy to be useful. And at low power levels is easily defeated. Reflective surfaces, etc. More over, lasers degrade quickly in atmosphere. Cohesion, range and destructive capability fall off quickly. We could get into the math, but I suspect that it was simpler for MWW to dismiss lasers and retain a higher energy kinetic weapon. The kinetic energy of the darts is more than destructive enough to accomplish the tasks likely to be needed. They also scale up relatively easily when you start considering tribarrels and the like.

In short, for most purposes, a pulsar is smaller, less expensive to build/operate, and uses less power the a laser weapon.

Lasers lose effectiveness if they have to pass through anything that absorbs, reflects or refracts light, such as fog, rain and smoke, all of which have an annoying habit of cluttering up terrestrial battlefields.

And that's just the environmental possbilities. Know your enemy is firing lasers, right before poking your head up out of a trench you could do anything from throw a craptop of dirt, to spraying aerosol cans among countless other effects. They have some laser weapons in the Furies series, but they're the laser version of SAW's, so it'd be a minimum of a tribarrel for Honorverse. A full up backpack, probably with one or two of the pinnace hip-pocket fusion bottles, and it'd be a 2m long 'rifle' complete with bipod/tripod for stabilization. But they also have chameleon 'cloth' in the Furies series, and in Honorverse nothing smaller than battle armor has it. The chameleon surfaces of battle armor might degrade lasers, and when you count in all the possible environmental and military possibilities to deflect & degrade lasers in addition to chameleonic surfaces, you'd be shining a high-power laser pointer for all the 'damage' you'd actually do. Perhaps useful if you're trying to lase targets for airstrikes, but otherwise you're lucky if you temporarily blind a few people.
