266nm Lasers, specifically Diode-Pumped Solid-State (DPSS) Lasers, utilize the fourth harmonic of Nd:YAG laser material at 1064nm. Given a particular laser, with a particular fundamental wavelength, fourth harmonic generation is less efficient and cannot achieve the same energy levels compared to its lower-order harmonic counterparts.

These high power, nanosecond 266 nanometer lasers are available with either free-space or fiber-coupled output and a variety of pulse energies depending on the applications needs.

Controllable Fixed rep. rate, such as 1k, 2k, 3k, 4k, 5kHz, with stable laser pulses emitting (stable pulse energy, peak, duration and period);
Different rep. rate in th Rep. rate (kHz) the range of 1kHz-5kHz can be obtained by input an external TTL signal;
Uncontrollable: Undefined rep. rate among 5k-7kHz and unstable laser pulse emitting. Suitable for the applications only needing high peak power pulses;

Average power (mW): Average power (mW) = Single pulse energy (μJ) * Rep. rate (kHz)

Because of the Walk-off effect of Nonlinear crystals, the beam quality of UV laser is not so good as that of 1064/532nm laser.

Applications:
Raman measurements,  Optogenetics, Laser Induced Breakdown Spectroscopy, Time-of-Flight Spectroscopy, Photoluminescence.

266 nm Beam Splitting Principle as following:

It can be Passively Q-switched and Actively Q-switched
