…(OPSLs) offer slower modulation (max values: 50 kHz digital, 100
kHz analog) with similar (50:1) dynamic range, and DPSS lasers do not support
modulation at all. Thus, depending on the
laser type, direct modulation is often possible. However, direct modulation is often
not a…

…intrinsic linewidth of a DPSS
laser. The intrinsic linewidth of a vanadate laser is just a fraction of a Hz.
The time-averaged spectral linewidth is broadened by wavelength jitter. There are various
mechanisms with different time domains that modulate the wavelength, so the measured…

…mode noise becomes a real problem.
Figure 2. In a CW DPSS multimode laser, the total power is constant even though it is dynamically
distributed between different longitudinal modes. When a doubling crystal is inserted in the DPSS
cavity, it causes chaotic fluctuations in the total…

…Q-switch device is an acousto-optical modulator or an electro-optical modulator (EOM). Both use crystals where an applied electric field produces
some perturbation of the optical properties of the crystal. In the case of acousto-optical modulators, the applied electric field is a…
