CartSWIR Lasers Overview
SWIR, Short Wavelength Infrared, laser sources include the wavelengths from 1.4μm –3 μm and are diverse category of solid-state lasers; with laser diodes, diode-pumped solid-state (DPSS) lasers, both CW and pulsed, fiber lasers and fiber amplifier all emitting in the SWIR spectrum. As a result, these lasers are available with both single-mode and multi-mode beam profiles, and with either free space or fiber coupled outputs. SWIR lasers are ideal for many applications in the Defense markets and are widely used in telecom applications. Short Wavelength Infrared pulsed lasers are also available with an extensive range of pulse widths and peak powers. SWIR fiber lasers cannot only produce high output powers, but they are also able to provide extremely narrow linewidth (and therefore long coherence lengths) making them ideal for a wide variety of lidar applications. OEM packages and modules are available for both DPSS and diode lasers.
The Q-TUNE-IR uses an Optical Parametric Oscillator (OPO) to produce tunable wavelength in 1380 – 4500 nm range with a linewidth less than 10 cm-1, achieving > 6.5mJ of pulse energy @ 3500nm for the F-10 configuration (> 2mJ @ 3500nm for C-10) with a 10Hz repetition rate. A broadband version with linewidth up to 200 cm-1 is also available by request. The Q-TUNE-IR requires little maintenance, with all laser electronics integrated into the housing, including an air-cooling system, eliminating the need for chillers, or large power supplies, all while providing a guaranteed pump diode lifetime greater than 2 giga-shots.
The Quantas-Q-SHIFT family of Q-switched DPSS lasers feature a built‑in nonlinear wavelength conversion stage, allowing the production of wavelengths that are not accessible with conventional solid-state laser sources, including 1163, 1177, 1300, 1317, 1551 and 1571nm. An optional harmonics generator is also available for for the Q-SHIFT, allowing generation of up to the 4th harmonic for each fundamental wavelength.
