Diode Laser Systems Replace Gas Laser Tubes
Instrument makers are transitioning transverse mode teaching kits from helium-neon gas laser tubes toward diode laser sources, eliminating the alignment maintenance and gas tube replacement cost that historically consumed significant laboratory technician time each semester and academic term. Diode-based kits now represent an estimated 55 percent of new unit shipments, up substantially from a decade ago when gas laser tubes dominated nearly every teaching laboratory configuration. Vendors offering diode systems with equivalent mode purity to legacy gas lasers increasingly win institutional contracts over competitors still centered on gas laser product lines.
