Non-thermal laser ablation is a process which is rapidly growing in popularity as the cost of picosecond and femtosecond lasers are becoming more available. Traditional laser ablation methods cannot be utilized to produce high tolerance machined parts of with such small feature size, due to the heat generated in the ablation process. As a result, it is necessary to utilized ultra-fast lasers which have an electric field density large enough to generate a Coulomb explosion. This explosion caused by short pulse non-thermal ablation lasers can remove the material via a “cold ablation” process, therefore, preserving the integrity of the surrounding material. In addition to the tolerancing advantage of Coulomb explosion in comparison to thermal ablation, there is the added benefit that since this is an electronic effect there is no need to take the materials absorption properties into account making this a wavelength independent process. On this page, you will find a list of all of the non-thermal lasers we offer at RPMC, including both picosecond and femtosecond lasers.

The ALTAIR series produces high average powers up to 20W and ultrashort femtosecond pulses of <150 fs (<250 fs for VERSA configuration) at a high repetition rate of 80 MHz (others available). Ideal for bioimaging/biophotonics applications such as multiphoton microscopy, the ALTAIR provides high stability and excellent beam quality due to its mode-locked fiber design. It offers a range of options such as GDD pre-compensation, custom wavelengths, harmonics, repetition rates, and more. With a simplified fiber design that requires little to no maintenance compared to DPSS and Ti:Sapphire counterparts, the ALTAIR is the preferred solution for both OEM and researchers in the microscopy and life sciences fields.
The ANTARES is a series of high-energy picosecond lasers designed for ease-of-use and integration in biophotonics and nonlinear spectroscopy applications. With a narrow linewidth, high repetition rate up to 80 MHz, excellent beam quality, and average powers from 1W to 40W at 1030 nm or 1064 nm, ANTARES is ideal for high-speed nonlinear spectroscopy applications such as CARS and FRET microscopy. Additional options include fine-tuning PRF synchronization, ultra-narrow linewidth, second and third harmonic options, custom repetition rates, and more.
The DIADEM series is a compact, versatile, air-cooled, high-energy, ultrafast femtosecond laser, operating at 1030 or 1064 nm for advanced micro-machining applications. Available with up to 40µJ of pulse energy, pulse widths down to ≈ 400 fs, an M² < 1.2, and single-shot up to 2MHz repetition rate, the DIADEM has many pulse control features such as adjustable pulse duration, selectable repetition rate from 40 MHz down to single-shot, or fine pulse energy tuning so that pulses can be emitted in various modes (on demand via external signal, burst of pulses with configurable pulse separation). A 1300 nm version is also available for deep brain imaging.
The SIRIUS series is a very compact, high-energy hybrid ultrafast laser for advanced micro-machining applications and supercontinuum pumping, offering over 60µJ and > 5 W @ 1064 nm, with pulses below 10 ps from single shot to 1MHz and an M² of < 1.2. SIRIUS is a fully configurable laser offering various pulse generation modes: selectable pulse durations and repetition rates, burst, gating and fine energy control. This laser series is specifically designed to allow for ergonomic and user-friendly operation. Also available in green or UV wavelengths, SIRIUS is ideally suited for selective ablation, electronics, and photonic applications.
