Pulse Width Range: 0.5ns- 3ns Peak Laser Current [@PW=3ns;24V;Can Be Increased on Request]: 2A (@PW=3ns) Bias Current [Can Be Increased to 100mA on Request]: 0 - 50mA

Continuously tunable pulse width:0.5ns-3ns. The STO-LDa-3 seed-laser assembly is an integrated solution for the seed-source (oscillator) section of pulsed MOPA fiber lasers. It includes an adjustable pulse-width generator, laser power supply, TEC controller, and integrated laser diode. Each rising-edge input trigger produces one pulse. Width is adjustable from0.5ns to above3ns; an onboard trigger generator is optional. Analog inputs control pulse width, bias current, and set temperature, with amplitude control also optional. Each analog input can be replaced by an onboard potentiometer for external control or internal settings. Bias-current adjustment affects spectral width or extinction ratio. Wide-temperature, maintenance-free operation suits commercial and industrial integration. Compatible diodes for STO-LDa-3 include DFB, FP, and FBG types at1030nm,1064nm,1310nm,1480nm,1550nm, or custom wavelengths, in industrial butterfly or coaxial packages.

The mid/far-infrared frequency converter extends the tunable frequency converter's range to16 µm. It provides tens of milliwatts average power between5 and10 µm and still delivers a few milliwatts at15 µm. Module pumping provides near-transform-limited pulses while retaining the pump source's excellent wavelength and power stability. It is specifically designed to avoid beam-pointing problems during wavelength tuning. Fully enclosed, it can be purged with dry air or nitrogen to reduce atmospheric absorption. The basic version is manually operated and includes a calibrated wavelength table. Automated versions or specially designed MIR modules are available on request.

Wavelength Range: min:920nm; max:980nm Conversion Efficiency: min:30%; max:50% Average Power: min:300mW; max:800mW

High output power, beam quality, and near-transform-limited pulses from Stuttgart Instruments make these sources ideal frequency-conversion pumps. Alpha-HP's broad tuning, stability, and automation enable a compact second-harmonic module for NIR signal wavelengths. Output of hundreds of milliwatts is attainable over the 720-980 nm Ti:Sapphire range. The VIS module provides fast, repeatable spectral tuning with stable pointing and can also operate with Alpha or a custom system. Narrow-linewidth/picosecond options are available.

Alpha-SRS is an ultralow-noise, fully automatic laser system for coherent Raman-scattering microscopy. Solid-state femtosecond technology achieves the shot-noise limit above 1 MHz modulation frequency. Tunable 750-950 nm and 1.4-2.0μm outputs plus a fixed 1043 nm beam support coherent Raman microscopy over 1015-3695cm -1 and multiphoton excitation microscopy. Custom pulse durations from 100 femtoseconds to picoseconds allow efficient excitation and spectral resolution down to 13cm -1. All three outputs are intrinsically synchronized;Stokes and pump beams overlap spatially and temporally with precisely adjustable delay. For SRS-microscopy, the pump has external modulation with 100% depth.
