A job shop running two full shifts, a customer threatening to cancel, and a laser marker that couldn't get the job done. That's not a hypothetical — it's what Laser Industries, an Orange County, California marking shop, was facing when they called Jimani.

Quick Answer
A fiber laser can be dramatically faster than a YAG laser on thick-plating marking jobs. In this Laser Industries case, the YAG laser took more than five minutes per part and produced roughly 25% scrap, while a 20-watt Jimani fiber laser system marked the same part in 42 seconds with zero scrap.
Their YAG laser was taking more than five minutes to mark each part, rejecting one in four as scrap due to incomplete penetration through thick plating, and capping output at 150 parts per day no matter how hard the crew pushed. A 20-watt Jimani fiber laser system marked the same part in 42 seconds with zero scrap. This is the story of how that happened, and what it means if your shop is dealing with a similar bottleneck.
YAG lasers fall short in high-volume production jobs involving thick or inconsistent plating because their beam quality and wall-plug efficiency create compounding limitations — slower speeds, higher heat input, and inconsistent penetration that becomes a scrap problem at scale.
In Laser Industries' case, the parts required marking through plating of varying thickness. The YAG laser couldn't generate enough peak pulse energy to cut cleanly through the thicker plated areas. The result was that roughly 25% of parts came off the line with marks that failed inspection. That's not a minor inefficiency — that's a quarter of the day's output going into the scrap bin.
The cycle time problem was equally serious. At over five minutes per part on two shifts, the shop was capped at about 150 parts per day. Their customer had contracted for a volume that required more, and when Laser Industries couldn't deliver, the customer started looking at second-sourcing the job — or canceling outright.
The core issue with YAG lasers in this kind of application comes down to physics. YAG lasers require 4–5 kilowatts of wall power to produce 20 watts of useful laser output, and the excess energy is dissipated as heat that the system has to manage. Fiber lasers produce that same 20 watts from roughly 200 watts of wall power, and the difference in wall-plug efficiency translates directly into a more stable, consistent beam that can do more work per pulse. When you're trying to mark through thick, inconsistent plating on a production timeline, that efficiency gap matters.
The same marking job that required over five minutes per part on a YAG laser was completed in 42 seconds on a 20-watt Jimani fiber laser system — a reduction in cycle time of more than 85%, based on Jimani's production testing at our Oxnard facility.
That number is not a specification sheet claim. Jimani programmed the Laser Industries job on our own equipment before any commitment was made. We ran the parts ourselves, confirmed the cycle time, and confirmed that even the thickest plated parts marked cleanly with zero scrap. Then we invited Laser Industries to send parts and run production at our shop while their new equipment was being built.
At 42 seconds per part instead of five-plus minutes, the math changes dramatically. A shop running a single shift at 42 seconds per part can exceed what Laser Industries was managing across two shifts on the YAG. That's not a marginal improvement — it's the difference between keeping a major customer and losing them.
The ability to penetrate thick plating consistently is a function of pulse energy. Jimani's fiber systems operate at the maximum allowable pulse energy for the laser's power rating — in a 20-watt fixed pulse width fiber laser, that's approximately 1 millijoule per pulse at 20 kHz. That peak energy per pulse is what allows clean ablation through difficult surface coatings that would cause a lower-efficiency system to fall short and produce rejects.
Jimani programmed the job, verified the results, opened the facility to Laser Industries for production runs, and then loaned them a complete fiber laser system to take back to their shop over the weekend — all before the 50-watt unit Laser Industries had ordered was even built.
It's worth saying plainly: Laser Industries was a competitor. They ran a job shop in Orange County that competed for the same marking work Jimani's job shop pursues. That didn't change the calculation. Jimani had sold them a 50-watt fiber laser system with a lead time that extended months out, and in the meantime, their biggest customer was about to walk. The right thing to do was solve the immediate problem, not wait for the paperwork to close.
Jimani built the marking job on a 20-watt fiber system, ran it at the Oxnard facility to verify cycle time and quality, and then let Laser Industries run production there while the 50-watt was in production. When it became clear that even that arrangement wasn't enough to fully satisfy the customer's schedule, Jimani sent Laser Industries home that Sunday evening with the 20-watt system — with the agreement that when the 50-watt arrived, Jimani would come out and swap the systems.
This kind of response is only possible because Jimani operates both as a systems manufacturer and as a working job shop. The equipment isn't in a showroom — it's in daily production use. When a customer has an urgent application problem, we already have the setup, the fixturing experience, and the process knowledge to run their parts and demonstrate what the system can actually do. That's a different kind of proof than a demo with sanitized sample parts.
If your laser marker is creating a throughput ceiling — whether from cycle time, scrap rate, or inability to mark through difficult surface treatments — the first step is running a production test on representative parts, not evaluating specification sheets.
Specs tell you what a system is rated for under ideal conditions. A production test on your actual parts, with your actual marking requirements, tells you what the system will do on the floor. When Laser Industries had a 25% scrap problem and a five-minute cycle time, those numbers came from real production, not from a worst-case scenario. The 42-second cycle time and zero-scrap result came from real production too — just on different equipment.
If you're running into a similar wall with an existing YAG system, or evaluating whether a fiber laser makes sense for a specific application, Jimani's job shop is a direct resource. Send us parts and a marking requirement. We'll run them, show you the results, and give you honest numbers on cycle time and quality before any purchasing decision gets made.
