Laser Products – Optogama

Lasers are highly precise light sources that generate a narrow, coherent beam of light. Unlike traditional light bulbs, lasers emit photons in phase and in the same direction, which makes them uniquely suitable for applications requiring accuracy, stability, and power efficiency.

Optogama specializes in compact, robust, and application-oriented lasers. Their portfolio focuses on "eye-safe" erbium-doped glass lasers at 1.54 micrometers (µm) and solid-state neodymium-doped yttrium aluminum garnet (Nd:YAG) diode-pumped solid-state (DPSS) lasers at 1064 nanometers (nm) or frequency-doubled 532 nm. Products include both nanosecond (ns) pulsed lasers with passive quality factor (Q) switching and continuous-wave (CW) erbium lasers.

These systems are designed with size, weight, and power (SWaP) optimization in mind, making them ideal for portable, aerospace, and field-deployed instruments.
