Solid-state resonator simulation
ASLD offers a user-friendly graphical interface for thermal and structural analysis, crucial for calculating thermal lens effects in laser crystals. Its 3-dimensional Finite-Element Method (FEM) accurately models long or thin laser crystals and small pump lights, considering frequency-dependent absorption and spectrum of pump light. With ASLD, designers can explore various crystal geometries and cooling methods, such as slab, oblique face, cylinder, and pyramid, streamlining the design process.
ASLD calculates output power and beam quality based on beam radius, pump/resonator configuration, and optical elements like apertures and output couplers. It simulates population inversion in laser crystals, capturing the time dynamic behavior of the laser through rate equations for different Gaussian modes. This analysis enables designers to optimize performance while ensuring stability.
Laser amplifier simulation
ASLD simulates ultra-short pulse amplifiers, multipass amplification, saturation effects of pump light absorption, temperature dependent cross sections, and 3-dimensional population inversion. It can accurately model output power and gain based on the pump configuration. ASLD incorporates effects like gain guiding and Kerr lensing, utilizing methods for beam shape simulation and ray tracing for defining pump light distribution. ASLD's pump light analysis accounts for pump light spectrum, polarization, and absorption within laser crystals, crucial for designing end- and side-pumped geometries.
Flexible definition of rate equation systems
ASLD's rate equation systems facilitate the simulation of resonator modes, including co-doped materials and various interionic mechanisms like upconversion and energy transfer. Users can customize rate equations through an intuitive GUI, accurately modeling resonator dynamics and thermal lens effects in laser crystals. ASLD accommodates gain mediums like Nd:YAG, Ho:YAG, Er:YAG, Er:glass, and Tm, Ho:YAG, considering multiple levels, temperature-dependent emission cross-section, and reabsorption.
Active and passive Q-Switch simulation
ASLD enables analysis of active and passive Q-switches, simulating pulse energy, pulse width, frequency, and beam quality. Its algorithms accurately model physical effects of passive Q-switching with saturable absorbers, considering properties like absorption cross-sections. ASLD simulates mode competition in the resonator, ensuring comprehensive design optimization.
Simulation of laser polarization effects
ASLD allows to simulate depolarization effects in laser amplifiers. Depolarization is calculated by a 3-dimensional finite element analysis and local Jones matrix analysis. The simulation results help to find the optimal crystal cut and pump configuration, in order to minimize depolarization effects. Low depolarization effects are needed for example for an optimal second harmonic generation.
