The Spectra‑Physics Model 130 Laserplane is a compact precision gas laser used for industrial and scientific applications. Common failure modes include loss of output power due to depleted or contaminated gas supply, misalignment of the internal optical path, and degradation of the resonator mirrors or beam steering optics. Additionally, electronic control boards may fail from over‑temperature cycling or power surges, leading to erratic pulse timing or shutdowns. For first‑check diagnostics: verify that the gas cylinder pressure is within spec and inspect for leaks; visually examine the laser tube and mirror mounts for misalignment or damage; review the controller’s error logs for temperature or voltage fault codes.[oss-gpt-20b]
