Description

Professional, silicate type Nd:glass laser rod, 14.5 mm dia. x 280 mm length, both ends at Brewster angle, new, never used, no original box.
Because of Brewster ends, the effective pump length is about 240 - 260 mm.
No defect, pictured each end. Vintage, mid 70', silicate Nd:glass laser rod, type GLS-1, made in Russian Federation.

Best to be used as an amplifier. Used as an oscillator, expect cca. 20 J - 40 J in free running, or cca. 12 J - 18 J in Q-switch, appropriately pumped. Good for industrial, scientific, educational lasers, or as laser history collectible.
