Pulsed DPSS Lasers use laser diodes as the pump light (pump source) for a laser gain medium. Unlike CW lasers that emit a continuous beam of energy, pulsed lasers utilize pulse generation techniques like mode-locking or q-switching to produce high peak power or high energy pulses with a lower duty cycle by storing energy within the cavity and releasing it in short pulses. Pulsed DPSS Lasers take advantage of the relatively narrow spectral linewidth of diode lasers in conjunction with their high brightness in order to maximize absorption and therefore increase efficiency. Pulsed DPSS lasers are also far more compact and require less maintenance than flash lamp-pumped lasers. DPSS Lasers can also benefit from second, third, fourth, and even fifth harmonic generation, allowing wavelengths from the UV to the IR spectral regions.
Our pulsed DPSS lasers are available in multiple wavelengths. For example: UV, Violet, Blue, Green, Yellow, Red, NIR, SWIR, and MWIR regimes. Firstly, we have options for active or passive Q-switching in the nanosecond (ns) and picosecond (ps) pulse width range. Secondly, pulse energy from 25nJ to 200mJ, and repetition rates ranging from single-shot to 80MHz are available. Finally, OEM DPSS laser packages and module options are available. Diode-pumped solid-state (DPSS) lasers are a category of optically pumped lasers. These lasers utilize a diode laser as the excitation source to pump a laser crystal (e.g., Nd:YAG or Nd:YLF crystal). DPSS lasers take advantage of the relatively narrow spectral linewidth of diode lasers in conjunction with their high brightness in order to maximize absorption and therefore increase efficiency.

One of QLI’s crucial innovations is its TEC-based water-free laser crystal cooling technology, combined with laser diode end-pumping. The absence of water results in a compact, user-friendly turnkey laser system that requires minimal maintenance compared to traditional water-cooled lasers that require large chillers and bulky power supplies. This enhancement eliminates the risks associated with water cooling, reduces the overall operating cost, and provides for an even more compact and efficient cooling design. The laser diode end-pumping technique provides enhanced cooling ability along the the length of the gain medium.
Expert Solutions for Your PCB Processing Applications
DPSS vs. Fiber Lasers
Fiber lasers are compact, rugged, reliable, & reasonably priced. So, why choose DPSS over fiber? DPSS lasers provide the same benefits fiber lasers offer, plus a host of additional benefits, allowing the versatility, precision, and quality you need for a vast range of applications. The DPSS lasers from Bright Solutions boast a rugged, fixed laser cavity design, resulting in a compact and reliable laser. Shorter pulse widths inherent to DPSS lasers result in higher peak powers with less heat affected zone (HAZ). With integrated doubling and tripling harmonic crystals, DPSS lasers enable easy access to more wavelength options (e.g. 532nm) and therefore, more application capabilities. Finally, Bright Solutions continuously improve their products and offer extensive customization to further benefit your application.
Why is a Low Jitter Feature Important in Actively Q-Switched DPSS Lasers?
In actively Q-switched lasers, the user controls the pulsed laser output, so that no laser pulse emission occurs without providing a proper input signal, aka “the trigger”. Due to the trigger signal propagation through the interface electronics, the Q-switch driver chain, and the laser resonator build-up time, a time delay (Td) is present between the externally-supplied trigger signal and the actual laser pulse (nanosecond or picosecond) emitted by the laser source. The Td can show fluctuations if any electronics or optics involved in the pulse generation process have a functional variance in time.
The parameter Td is very relevant in the timing management of some applications. You must consider both the time delay (Td) and a time jitter (Tj), which is a statistical variation of the time delay depending mostly on:
electrical noise in the trigger-chain
pulse-to-pulse fluctuation of trigger-chain electrical parameters
laser pulse build-up time-mechanism and associated fluctuations.
fluctuation of rising (-falling) edge temporal profile of the trigger signal

What is a Thin Disk Laser, and What Advantages do They Offer?
A thin disk laser is a type of diode-pumped solid-state (DPSS) laser technology in which the gain medium is comprised of a thin disk of typically Yb:YAG crystal. The thickness of one of these disks (typically 150µm to 200µm thick) is substantially smaller than the beam diameter. This feature allows not only the ability to easily scale up power via pump beam diameter, but also provides a large surface area for heat dissipation. One entire surface of the thin disk is mounted to an actively-cooled heatsink, which efficiently draws heat out axially or longitudinally, rather than transversely. The back surface, mounted to the heatsink, is coated to reflect both the pump and laser radiation. The beam from the pump laser is collimated, directed toward a parabolic mirror, and then reflected back toward and through the thin disk. The pump beam is then reflected off the back, coated surface of the disk, back to the parabolic mirror. This process repeats, allowing the beam to pass through many times until lasing occurs.
