A wide range of diode-pumped actively Q-switched lasers with pulse durations around 1 ns are offered by ALPHALAS. They feature high peak powers at various wave-lengths in the infrared, visible and ultraviolet as well as excellent TEM₀₀ beam profile.
The PULSELAS®-A series lasers imple-ment proprietary Pockels cell design for generating extremely short laser pulses. The semi-monolithic laser cavity is permanently aligned and therefore extremely stable.
The multi-kilowatt laser pulses can be as short as 500 ps and have a jitter to external signal of typically 500 ps, with option down to 200 ps.
High-energy amplified laser systems (MOPA) deliver more than 1 mJ pulses resulting in the highest peak power >1 MW with pulse widths below 1 nanosecond.
Models with repetition rates from 10 kHz up to 100 kHz and average power ranging from 100 mW to >1 W are available.
The standard models with wave-lengths 1047, 1053, 1062 and 1064 nm are complemented by lasers operating at 946 and 1342 nm with pulse durations <5 ns. Optional frequency conversion to red (671 nm), green (532 nm), blue (473 nm) and ultraviolet (355 nm or 266 nm) is also available.
The compact design is perfectly suited for almost any system integration.
These unique lasers have an ex-tremely broad spectrum of applica-tions ranging from supercontinuum generation in photonic crystal fibers to laser-induced breakdown spectroscopy.

Notes:
¹⁾ Fiber-pumped laser head.
A built-in frequency generator and external TTL triggering are standard features for all models.
All models are available with options for frequency doubling, tripling and quadrupling to 532, 355 and 266 nm.
Customer specific parameters are available upon request. Please contact us for further information.
Specifications for customer specific products are subject to change.
Regulatory Requirements Compliance
The PULSELAS® series diode-pumped solid-state lasers are OEM products intended for inte-gration into other systems.
They do not comply with CDRH requirements. The customer is responsible for CDRH certification of the system incorporating
the PULSELAS® lasers.
