Nanosecond lasers offer high peak power, multi-wavelength options, and compact air-cooled designs, making them ideal for LIBS. They excite stable plasmas on solids, enabling ppm-level multi-element detection. Domestic microchip ns lasers (>10 mJ,

Diode lasers offer narrow linewidth (

Semiconductor lasers offer wide wavelength range, compact size, long lifetime, and low cost, making them ideal for handheld Raman spectrometers. These portable devices enable rapid, non-destructive on-site identification of substances—from narcotics and explosives to food adulterants and pharmaceuticals. Applications span public security, food safety, environmental monitoring, and geology. Emerging organic semiconductor breakthroughs promise further sensitivity gains, expanding future use cases.

RealLight's Raman probes enable non-destructive, real-time material analysis across pharmaceuticals (PAT, API verification), petrochemicals (reaction monitoring), lithium batteries (electrode evolution), food safety (pesticides, adulteration), and forensics. Featuring high sensitivity, industrial-grade stability, and customizable options (immersion, high-T/p, SERS), these fiber-coupled probes support lab and harsh-field applications.

Multi-wavelength diode lasers enable sensitive bio-tissue analysis via spectral, imaging, and biosensing. RealLight’s AWSO-B offers 36 channels, TEC control (0.3nm/°C), and flexible output for reliable detection.

Handheld Raman lasers (532–1064nm) use narrow-linewidth diodes. Single-mode enables micro-analysis; multi-mode offers higher power. Wavelength choice balances fluorescence and signal. RealLight provides compact modules for advanced detection.
